Browser Extension & Full-Stack Developer | Manifest-V3 React Supabase

I build browser extensions people actually keep installed, plus the full web apps behind them. Top Rated Plus, 100% Job Success, $100K+ earned across 29 projects — and unlike most, I can show real user traction, not just screenshots. What I build: - Chrome, Firefox & Edge extensions on Manifest V3 — service workers, content scripts, cross-browser support, Chrome Web Store approvals & compliance - MV3 migrations and rescues — broken service workers, rejected submissions, deprecated APIs - Full web apps end to end — React + Vite, Node, Supabase, deployed on Vercel — so the extension and its dashboard, auth, and billing come from one person Recent work: - Supademo — extension live with 40,000+ users - Spot N Paste — 1,000+ paying customers - Multi-platform desktop + browser app with Whisper transcription and FFmpeg editing Why clients keep me: - One accountable developer — no agency handoffs, no "let me check with the team" - Replies within a few hours, with regular progress updates instead of silence - A straight "no" when something isn't feasible, before you spend budget on it We're a good fit if: you need an extension built, fixed, or migrated to Manifest V3 — or a small-to-mid web app shipped fast by someone who won't disappear. Send me what you're building and I'll tell you honestly whether I'm the right person for it.
