Arshdeep Singh
Full-stack Developer · India
Summary
Solo full-stack developer. I take a project from an empty folder to something live on the internet: the design, the code, the app, the server it runs on. Then I keep it alive. No agency, no team. Most of what I've built is in production right now, used by real people. I write my own crypto, run my own VPS, and ship the whole thing myself.

Selected work
Zero-knowledge file and text drops. Everything is encrypted in your browser before it uploads, and the key lives in the link fragment, so the server only ever stores ciphertext it cannot read. AES-GCM through the Web Crypto API, expiring links, burn-after-read, and syntax-highlighted code pastes. It also ships veil, a page that tucks encrypted messages inside ordinary images. I self-host the whole thing on my own VPS.
An open-source, end-to-end encrypted messenger. Messages get locked in your browser before they ever reach the server, so a database leak would only spill gibberish. I wrote the whole crypto layer myself with the Web Crypto API: real accounts, a key directory, and live realtime chat. The code is public.
A platform for a startup that helps Indian students figure out what to do right after their board exams. I built the site and led the redesign.
A webring I started and run: a small ring of personal sites that link to each other the old-web way, so people hop between them instead of trusting an algorithm. I built the site, the hosted theme-aware badges, and an automated health check that pings every member and shows who is up. Invite-only, five sites so far.
A creator community's site that shows every member's live YouTube subscriber count. 17 channels, updated automatically every hour.
A creative agency I run with a friend, aimed at anime and manga brands. I built the whole site: a 3D hero in Three.js, a live chat widget, and a Supabase backend that runs our lead inbox. We pitch studios manga-first.
What I build
- Websites. Fast, modern sites that look good and actually show up on Google. Business sites, landing pages, web apps.
- Mobile apps. Android apps, built and published to the Play Store. Bookings, payments, notifications, all of it.
- Backend & servers. The part nobody sees: databases, APIs, and the server that keeps everything online. I set it up and I keep it alive.
