Senior Full-Stack Engineer — Node.js · TypeScript · React — building and shipping LLM-powered products end-to-end.
10+ years across backend and frontend. By day, senior engineer at DISQO, building NestJS services and React frontends for a high-traffic consumer-insights platform. Off the clock, I design, build, and ship real products solo — two are live on the App Store.
- Steady — Parenting SOS & Calm — React Native / Expo app with an LLM backend generating real-time, context-aware co-regulation guidance. Auto-renewing subscriptions, Sign in with Apple, privacy-by-design — owned in production. → App Store
- Exhale — Stress Painkiller — one-tap, evidence-based guided breathing, localized in 7 languages, with server-authoritative subscription gating. → App Store
- loopscore — an eval harness that scores whether a coding agent genuinely fixed a bug or cheated its way to a green test suite. No model in the scoring path; 68 offline tests.
- claude-gist — adaptive output verbosity for Claude Code, with a code-enforced safety floor and conservative token-savings stats.
- Contributing bug-fix pull requests to supabase/supabase across Studio, pg-meta, and docs.
