I'm a self-taught, solo Android developer in Kolkata. I build production apps end to end client, edge backend, and infrastructure then close the laptop and build the same kind of systems in servos and sheet metal.
I taught myself Android development and now build and ship production apps independently no team, no handoffs, every layer my own.
My flagship project is VOID Messenger, a privacy-focused end-to-end encrypted messaging app. I own the whole stack: the Kotlin and Jetpack Compose client, a Cloudflare Workers + Durable Objects + D1 backend, Supabase for auth, Backblaze B2 for media, and an AI assistant, AXIOM, that I've integrated directly into the app on its own routing layer.
Before this, I spent 3+ years as a community manager, working on moderation strategy and engagement systems which is where a lot of my instinct for designing systems around real people's behavior comes from. A drawing background feeds the other half: it shapes how I think about interface layout, and now, how I think about physical form when I design hardware.
When I'm not writing Kotlin or Worker code, I'm usually at the print bed or the paint desk.
Privacy-focused E2EE messaging app with client-side vault messaging, group key rotation, and AXIOM a built-in two-tier AI assistant running on its own Cloudflare Worker.
Android home-screen widget for Codeforces heatmap, solved count, streaks, rating, and latest solve, all at a glance.
Published day-planning Android app, shipped solo end to end and available on the Play Store.
Group music sync app, currently being scoped for a web/Electron pivot to replace its Nearby Connections transport with WebRTC data channels.
Cross-device file transfer app layered over Nearby Connections, NSD, and WebRTC, with Firebase Realtime DB signaling.
Where the apps stop and the soldering iron starts. Two quadruped builds, currently in progress.
A quadruped robot dog, rebuilt on a repainted "100 Pet Dog" shell with merged firmware for voice control, an animated OLED face, and auto-docking.
An open-source quadruped spider, taken on first as a lower-risk build to learn gait control and wiring before committing to BUZO.
Have a project idea, a question about VOID, or just want to talk robotics and Android? I'd love to hear from you.
