Active Development Debian Stable KDE Plasma QML / Qt GPLv3

A privacy-first Linux OS, designed like a product.

Mission OS is a privacy-first, offline-first operating system built on Debian Stable and KDE Plasma, not "another distro," but a focused OS designed around four pillars: privacy-first, security-conscious, portable-first, offline-first. No telemetry, ever.

TELEMETRY CALLS

The Problem

Privacy-focused OSes look like they were built for hackers, not people.

Most privacy-oriented Linux distributions signal intent through aesthetics, dark terminals, green text, cyberpunk imagery. That's a signal to the wrong audience. It reads as "for experts only," and the UX usually lives up to it: unexplained toggles, dense options, security features you enable without understanding the trade-offs.

The result is a gap. If you want a well-designed, modern desktop OS that also treats your privacy as the default rather than an add-on, the market is thin.

The Solution

Product-grade design applied to a serious operating system.

Mission OS is designed around the principles of any modern product: clarity, consistency, careful defaults, honest explanations. The visual direction takes cues from Apple, Proton, Arc Browser, Linear, Vercel, and Nothing, dark graphite, slate, white, soft violet accents, cool blue highlights. Minimal, modern, premium, spacious.

Every advanced security feature in the installer explains its benefits, limitations, compatibility, and trade-offs. Users should understand what they're enabling, not just flip a switch.

Four Pillars

Privacy-first

Sensible defaults, honest choices, no telemetry, ever. Firefox and Tor Browser preinstalled; Brave and Chrome optional.

Security-conscious

Full disk encryption, Secure Boot, TPM, recovery keys, each explained in the installer, not hidden behind unlabelled toggles.

Portable-first

Designed to travel, installable on the machines you actually use, with sensible driver and hardware defaults.

Offline-first

Core system components work without a network. The OS assumes you might not have connectivity, and doesn't degrade when you don't.

Installer Experience

13 screens, each explaining trade-offs instead of hiding them.

The installer flow: Welcome → Language → Keyboard → Network → Privacy Setup → Disk Selection → Partition Manager → User Account → Encryption → Security Options → Summary → Installation → Completion.

Structure stays consistent on every screen: Header → Stepper → Main Content → Contextual Help Panel → Action Bar. Security Options is the centerpiece. Full Disk Encryption, Secure Boot, TPM, Automatic Updates, Recovery Key, and Emergency Recovery Media each get their own explanation of benefits, limitations, compatibility, and trade-offs.

Install Profiles & Privacy Profiles

Install profiles

Minimal · Developer · Security · Custom. Each preselects the packages, services, and defaults that make sense for the use case.

Privacy profiles

Balanced · Privacy · Advanced. Governs tracker blocking, default browser configuration, background service defaults, and cookie policies.

Core System Components

Mission Settings

Unified system settings, grouped, searchable, consistent across the OS.

Mission Store

Curated app catalog. Signed packages, honest metadata, no dark patterns.

Mission Update

Predictable system updates. Notify or automatic, always transparent about what changed.

Mission Recovery

Rescue mode and system restore. Designed to be usable when things are already going wrong.

Mission Driver Manager

Hardware compatibility surface, clear about what's supported and what isn't.

Mission Diagnostics

Local diagnostics only. Never phones home; results stay on your machine unless you export them.

Accessibility & Responsive Design

Every screen treats accessibility as a first-class requirement.

Light and dark themes, keyboard navigation with visible focus states, screen-reader labels, 44px minimum interaction targets, reduced-motion support, and full validation / loading / error / success / offline states across every screen. Responsive layouts split at wide ≥760px and compact <640px, hardened against a previously-identified 640–759px gap. No fake system actions in the UI. Minimum practical resolution: 1024×768.

Engineering & Testing

Documentation-first, tested end-to-end.

Stack: QML, Qt, CMake, QtTest, CTest, GitHub Actions. Documentation-first workflow with Architecture Decision Records (ADRs).

Validation status: MOS-INS-001 → MOS-INS-012 passed a full UI foundation audit, 14 CTest tests, 13 runtime suites, qmlsc explicitly skipped where unavailable, 54 visual captures, 141/141 pixel checks passed, accessibility / keyboard / theme / reduced-motion / 44px targets all passed, no regressions. MOS-INS-013 (Security Options, 12→13 steps) shipped with its own 18-test QtTest suite, status: PASS WITH DOCUMENTED GAPS.

A useful lesson from the audit: several apparent visual failures traced back to the measurement tooling, not the UI. The tooling was fixed and the actual pixels revalidated before any product changes were made.

Current Status & What's Next

Active development. Installer foundation validated end-to-end. Core system components (Mission Settings, Store, Update, Recovery, Driver Manager, Diagnostics) are in architecture and early implementation. This is not a shipping OS yet, no ISO, no release channel, no production hardware validation. Everything user-facing shown here is a labeled concept or development preview until real captures exist.

Public Beta Windows Desktop AES-256-GCM Fully Offline

Your private files, sealed behind one password.

Nexus is an encrypted personal vault for Windows, files, passwords, notes, bookmarks, and contacts, protected by AES-256-GCM authenticated encryption and stored entirely on your machine. No cloud. No sync. No internet connection, ever.

Join Beta on Discord → Get Beta Access

Lock Screen, the first thing every Nexus user sees

The Problem

Most "secure" tools still trust someone else with your data.

Password managers, note apps, file vaults, most of them are excellent at security in one narrow sense: encryption in transit. But the data still lives on someone else's server. A breach, a policy change, a shutdown, a subpoena, any of these can expose what was supposed to be private.

I wanted something different: a single vault for the things that actually matter, files, passwords, notes, bookmarks, contacts, that never leaves the device it's created on. Not "encrypted in the cloud." Not stored locally either. Built so there's no cloud to begin with.

DARK THEMES

The Solution

One vault. Everything sealed behind a single master password.

Nexus runs as a single portable file, no installer, no runtime dependencies. Download it, run it, create a vault. Your master password is the only one you need to remember; everything else lives behind it, encrypted at rest with AES-256-GCM and decrypted only in memory while the vault is unlocked.

Dashboard

Vault health, storage breakdown, recent files, and live security status at a glance.

Shown with demo data

Credentials Manager

Passwords, usernames, and built-in TOTP for two-factor codes, no separate authenticator app needed.

Secure Notes & Journal

Markdown-formatted encrypted notes, plus a private daily journal with a 30-day calendar view.

Zero-Trace Launcher

Run any app through Nexus in a monitored session, temp files are securely deleted when you're done.

Streamer Mode

Makes Nexus invisible to screen capture, OBS, and screenshots, your vault stays private even on stream.

Smart Collections

Auto-grouped views that surface related files, notes, and credentials across the vault without manual tagging or folder upkeep.

Multiple Vaults & Decoys

Run several independent vaults side by side, including decoy vaults, a real, separate vault that unlocks in place of your primary one.

Security, Made Visible

Trust isn't a claim, it's a status you can check.

Most encrypted apps ask you to trust them blindly. Nexus surfaces its own integrity constantly: a tamper-proof activity log with a cryptographic HMAC chain, a live vault integrity scan, and a real-time security panel, so "secure" isn't just a word in the marketing, it's a number you can watch update. Your master password never touches the vault cipher directly, it's run through Argon2id key derivation first, a separate, deliberately slow step from the AES-256-GCM encryption that actually seals your data, so brute-forcing the password is expensive even if the vault file itself is exposed. Nexus also plants honeypot bait files inside the vault: touching one logs the attempt as an intrusion rather than granting access.

Security Center

Challenges

Building "offline by design" is harder than it sounds.

01

No server means no easy recovery

Forgotten password with no recovery phrase saved means the vault genuinely cannot be unlocked, by design. Nexus offers a recovery phrase and a machine-bound bypass as fallbacks, but lose both and the vault stays sealed for good, an intentional tradeoff of true zero-trust, since there's no "reset password" email to fall back on.

02

Proving "we can't see your data" without a server to prove it on

Most privacy claims are backed by a policy document. Nexus backs it with architecture, zero network calls means there's no endpoint to audit because there's nothing to send. The activity log and integrity scan exist so users can verify this for themselves, not just take it on faith.

03

Designing a UI dense enough for power users, calm enough for daily use

A vault holding files, passwords, notes, journal, bookmarks, and contacts risks becoming cluttered fast. The v2 redesign reorganized the sidebar into Vault / System / Personal groups specifically to keep that complexity navigable without flattening it.

Current Status & What's Next

In public beta now. Full release this summer.

Nexus is in active public beta, license keys are free during this phase via Discord, and early Founder-status beta users keep free access permanently once the paid version ships. The v2 UI redesign covered in this case study is complete; remaining work is final auditing and polish before the public release.

v4.2.2 · Final Release Open Source · MIT Free Forever Windows / Electron

Your canvas. Your references.

Kanvaz is a visual research workspace for collecting, organizing, and connecting references, built the way artists actually work: a fast, distraction-free canvas, not a cluttered asset manager.

View on GitHub → Download Latest

A working board, reference cards, logo variants, and sticky notes, dropped and arranged directly on the canvas

Why It Exists

Built for the people I work alongside.

Before Kanvaz was a public release, it was a gift, built for the VFX and 3D community I'm part of, for the friends and teachers who needed a fast, no-friction place to drop reference images while working. Most reference tools are either too heavyweight or built for a different workflow entirely.

Kanvaz does one thing: give you a canvas, let you throw images, GIFs, and video references onto it, and stay out of your way.

"Built for VFX artists, 3D artists, and the people who teach them."

What's Inside

Simple on the surface, configurable underneath.

The canvas itself stays minimal by default, dot grid, drop zone, nothing competing for attention. But every detail of how it behaves is adjustable: autosave interval, default card sizing, whether double-clicking creates a note, even whether deleting a card asks for confirmation first.

Map View

Every reference, and how it actually relates to the others.

Settings

Every behavior is a toggle, nothing locked in.

Status

Actively developed, not "finished and abandoned."

Kanvaz is at v4.2.2, its final release. Board View, the Connection System, and Map View are all stable. v4 shipped a plugin system (window.KanvazPluginAPI, main-process consent dialog), URL and File reference card types, a safer .kanvaz zip container with per-asset SHA-256 integrity hashes, GitHub Actions CI, and an opt-in updater. Theme Creator ships as the first official plugin. Dev is winding down: no subscription, no feature paywall, no telemetry, no internet connection required. Your files never leave your machine, and it stays free forever.

Free, open source, and ready to use, no account, no sign-up.

What's next

Plugin system (v4.2)

window.KanvazPluginAPI, plugins register new card types, ship full alternate themes, add their own Settings panels. Every install goes through a main-process consent dialog; plugins can't self-approve.

Theme Creator (v4.2)

First official plugin: in-app theme editor, live preview, presets, one-click reset. Ships alongside the design-system audit that unified radii, shadows, and animation tokens across every modal and panel.

Safer .kanvaz save format (v4.1)

Moved from a giant base64-inline JSON blob to a real zip container with per-asset SHA-256 integrity hashes. ~33% smaller files; one damaged asset degrades gracefully instead of losing the whole board. Fully backward compatible.

URL & File reference cards (v4.1)

Two new reference card types on top of the original six. File cards block executable/script types on open for safety. No new dependencies, no telemetry.

About

Why I do both, and why I probably won't stop.

I'm Atharva Patil. I write software that encrypts and protects, build tools that help artists work faster, and study how to render light convincingly, all at the same time, all from Navi Mumbai.

Most people choose a lane. I haven't figured out why I should. The same instinct that goes into designing Nexus's lock screen goes into lighting a 3D scene, obsessing over how things feel when you interact with them, not just how they look. Kanvaz started as a tool I built for the VFX community I'm part of. Obscura started because Roblox developers deserve professional-grade tooling without a paywall. Every project comes from being inside the problem.

I run Northbyte Studios, a solo software operation. Everything ships free forever or open source. Not as a strategy. As a principle.

What I'm Building

Freelance Web & Brand Work

Independent client work spanning web development, UI/UX, and visual identity, including a full production website build for a performing arts academy.

How I Work

Scoped, not rushed

Every build starts with a plan and explicit confirmation gates, no surprise scope creep mid-project.

Privacy by architecture

Where it matters, "we don't see your data" is backed by zero network calls, not just a policy document.

Free where it should be free

Tools built for a community I'm part of stay free. Kanvaz and 3D Ref Skills are both free, forever.

Design and code, together

I don't hand off design to be implemented separately, the interface and the build happen as one process.

This Site

This page is a project too, not just a container for them.

One HTML file, zero build step, zero third-party runtime code except a font. Every claim below is something you can check yourself, not something you have to take on faith.

Accessibility, honestly stated →

A real self-assessment against WCAG 2.1 AA, what's implemented, and what genuinely isn't yet. No unverified compliance badge.

Live, not claimed

The widget in the bottom-left corner counts external requests, trackers, and cookies in your own browser, right now, check it against your own DevTools.

Versioned like software

Every shipped change bumps a visible build number, footer and console, because a portfolio is still a codebase, and codebases have history.

Nothing hidden

View source is one click away from that same widget. What you'd see is exactly what shipped, no minified bundle standing between you and the code.

Last updated: June 2026 · v2.0

Target

WCAG 2.1 Level AA. Not independently audited by a third party, this is a self-assessment, kept honest by listing specific gaps below rather than a blanket "compliant" claim.

Implemented

Every custom interactive element, the 7 expandable resume/project cards, the contact-page dropdowns, all buttons, nav, and links, is keyboard-reachable with a visible :focus-visible state, not just a mouse target with an onclick.
Resume/project cards use role="button", tabindex="0", and correct aria-expanded state, activated by Enter and Space as well as click.
The custom dropdowns on the Contact page follow the real ARIA listbox pattern (role="listbox", role="option", aria-selected, roving highlight via arrow keys) rather than a native <select> or an unlabelled div stack.
A skip-to-content link is reachable by keyboard and actually becomes visible on focus, it isn't hidden off-screen permanently.
All animation on the site (background effects, ring/logo motion, hero typewriter, card tilt) respects prefers-reduced-motion and disables itself accordingly.

Try it yourself

Rather than just claim keyboard accessibility works, here's a way to feel it directly - a live caption showing approximately what a screen reader would announce as you Tab through this page. Not a substitute for testing with real assistive tech, but closer than a sentence.

Known gaps, not yet fixed

Color contrast has not had a full pass yet, some muted text/border combinations are on the roadmap to verify against AA ratios, not yet confirmed.
This is a single-page app with in-memory routing (a deliberate tradeoff for portability, not an oversight), because every page's markup coexists in one DOM, there are multiple <h1> elements on one document at once, which can make the heading outline confusing for screen-reader users navigating by heading.
Navigating between pages updates the document title but doesn't yet move focus or announce the change via a live region, keyboard/screen-reader users won't get an explicit "you're on a new page" signal beyond the title change.

Report an issue

If something here doesn't work with your keyboard, screen reader, or assistive tech - email me directly. Real reports move up the list faster than anything on this page.

v4.0 Ultraviolet Cathedral redesign - full palette overhaul, PP Editorial New typography, em-dash purge, emoji-to-SVG icons

Major visual redesign - Ultraviolet Cathedral palette. Six-month stable target. Awwwards submission candidate. Palette and typography picked from lab previews after four rounds of iteration.

Palette. Deep ultraviolet 4-tier dark base (#0A0517 -> #150B25 -> #1F1338 -> #2B1B4F), replacing the flat #08080D. Cream text (#E8E1D0) instead of near-white, inverting the usual dark-portfolio pattern (cream-on-ultraviolet, not white-on-black-with-purple). Purple family widened: primary #B993FF (brighter), deep #7B3FE4 added. Reference: Locomotive studio pages, cathedral-scale editorial design.

Typography. Fraunces (taste-skill-banned default serif) and Inter (default LLM body sans) removed site-wide. Replaced with PP Editorial New (Fontshare, free) for both display and body, italic on emphasis phrases. Space Grotesk also collapsed into PP Editorial New. Single-family editorial stack, sacred-text feel. JetBrains Mono kept for code and status pills. New Content-Security-Policy allows api.fontshare.com / cdn.fontshare.com.

Em-dash purge. 234 user-visible em-dashes replaced site-wide per taste-skill anti-slop rule (word-em-word to word-hyphen-word; space-em-space-Capital to period-space; otherwise comma). Historical changelog comment block preserved intact.

Numbered section-labels retired. "01 Selected Work", "02 Open Source", "03 3D and Visual Work", "04 Services", "05 About" all lose the numeric prefix. The section is the label.

Emoji feature-icons -> inline SVG. 18 emoji icons on the Nexus and Mission OS case studies replaced with Phosphor-style outline SVGs (1.5px stroke, currentColor) for typographic consistency and screen-reader friendliness.

Deferred to v4.1: base64 image externalization (biggest single Lighthouse win, needs image extraction pipeline), signature hero interactive aurora, persistent NB monogram in nav.

v3.35 Content sync: Mission OS added, Nexus v10.12.0/AES-GCM, Kanvaz v4.2.2 final, Veris polish phase, misleading Nexus GitHub buttons removed

Content correctness pass, no design changes. The site was frozen at v3.34 for ~1 month while focus shifted to Nexus and Mission OS. Bringing every project surface back into sync with reality.

Mission OS, added as the first-featured project (Nexus moves to second). New /work/mission-os case study page covering the four pillars, installer experience (13 screens), install/privacy profiles, six core system components, accessibility & responsive design, engineering & testing (141/141 pixel checks passed on the installer foundation). Homepage card, /work project row, timeline, /status entry, console log, and footer nav all added. Media rule respected: no fabricated screenshots, one labeled concept placeholder for the Security Options screen; real captures land as they exist.

Nexus, version v10.12.0 surfaced everywhere. AES-256 references upgraded to AES-256-GCM to reflect the real cipher (v10.12.0's NXG1 format shipped real GCM; bare "AES-256" was misleading). Roadmap grid rewritten: dropped the false "public open-source release" promise (Nexus is proprietary per Resume), replaced with the actual v10.11–v10.12 features that shipped (in-app updater, AES-GCM upgrade, Windows Hello unlock, theme consistency pass). Both misleading "View on GitHub" case-study buttons repointed to the Discord beta invite.

Kanvaz, every "v3.7.1" / "v3 planning" / "v4.0 next milestone" replaced with v4.2.2 as the final release. Roadmap grid rewritten to describe what actually shipped: plugin system, Theme Creator, safer .kanvaz zip container with SHA-256 integrity, URL/File reference cards. Status pill now reads "v4.2.2 · Final Release," resume next-milestone reads "dev wind-down, no v5 planned."

Veris, badge and status corrected from "Released" (never was) to "Final Polish · Pre-v1.0.0" across the project row, resume panel, and /status.

repo-map, status corrected from "in development" to "on hold" per current reality.

Glint, real repo (github.com/p4inz-code/glint) now wired to the card; the card previously linked to the GitHub profile, which felt like a broken link. Copy updated to match.

Ticker, homepage "Currently:" strip updated with real current-state.

v3.34 Real browser Back/Forward, deep-linking, and an iOS input bug fixed

Implemented a Hybrid Router: Back/Forward now navigate in-app instead of exiting the site, direct links to sub-pages work on refresh, and scroll + focus position restore correctly, all with a safe fallback for sandboxed preview contexts. Fixed the About-page ring animation's mobile desync by making its SVG dashoffset resolution-independent (`pathLength=100`), with the exact same visual look preserved. Fixed a real iOS Safari bug: the Name/Email contact fields were stuck at 14px, under the 16px auto-zoom threshold, so typing into them on an iPhone would jerk the whole page to a zoomed-in state, bumped to 16px, matching the message field and dropdown, which were already correct.

v3.33 Nexus deep-dive, two real bugs fixed, scroll-to-top added

Rewrote the Nexus case study using the actual README/CHANGELOG/GitHub docs instead of generic copy, corrected status back to Public Beta, named the real Argon2id key-derivation step, added Smart Collections and multi-vault/decoy-vault details, and fixed the tech-stack listing to WPF (Avalonia is a planned future cross-platform build, not the current one). Fixed two genuine bugs: the nav could get stuck hidden after scrolling up, and the About-page stat counters stayed at 0 for anyone with reduced motion enabled. Also tightened the homepage headline and added a scroll-to-top button.

v3.21 Kanvaz content updated with real v3.6.9 release data

The Kanvaz case-study page previously claimed "development is complete, final release" and listed fabricated future features. Updated every mention site-wide using the actual v3.6.9 GitHub release notes and README, status, tech details, and a real roadmap (editable tags in v4, Map View wire-alignment fix) pulled from documented "known limitations," not guessed at.

v3.18 CLS regression fixed, mobile ring alignment bug fixed

Root-caused a real measured CLS of 1.032 to font-display:swap on the Google Fonts request, switched to font-display:optional, eliminating the late-reflow shift entirely. Also fixed a genuine mobile bug: the About-page ring elements weren't resizing with their container and were overflowing on small screens.

v3.16 Console error resolved, og:image prepped

Closed a console error open since v3.6, root cause was a view-source link attempting window.open('view-source:...'), which Chrome blocks at the browser level (not a catchable JS exception, so the fallback never ran). Also composed a proper 1200×630 social-card image, ready for when hosting goes live.

v3.1 Full accessibility pass

Made 7 previously mouse-only expandable cards fully keyboard-accessible, added :focus-visible site-wide, fixed a skip-to-content link that was permanently hidden off-screen, and unified two inconsistent badge components into one.

Full internal build log lives in this page's own source, see the Accessibility page for how to view it.

Software during the day. 3D and VFX when the day's not enough. This site is both.

Privacy-focused OSes look like they were built for hackers, not people.

Product-grade design applied to a serious operating system.

13 screens, each explaining trade-offs instead of hiding them.

Every screen treats accessibility as a first-class requirement.

Documentation-first, tested end-to-end.

Most "secure" tools still trust someone else with your data.

One vault. Everything sealed behind a single master password.

Trust isn't a claim, it's a status you can check.

Building "offline by design" is harder than it sounds.

In public beta now. Full release this summer.

What's next

In-app updater (v10.12.0)

AES-256-GCM upgrade (v10.12.0)

Windows Hello biometric unlock

Theme consistency (v10.11.0)

Built for the people I work alongside.

Simple on the surface, configurable underneath.

Actively developed, not "finished and abandoned."

What's next

Plugin system (v4.2)

Theme Creator (v4.2)

Safer .kanvaz save format (v4.1)

URL & File reference cards (v4.1)

This page is a project too, not just a container for them.
