A corner for the things I build for fun.
This page is my sandbox. I'll keep dumping random, half-built experiments here — some polished, most not, a few that vanish next week. Nothing here is meant to be permanent.
Real-time incident detection on any camera. Point your phone, an RTSP/ONVIF IP camera, or an uploaded clip at it — and it flags home-safety events (falls, prolonged stillness, danger-zone entry, presence/absence, off-hours intrusion) and traffic events (wrong-way vehicles, breakdowns, congestion, stray animals). Per-user login, private feeds, runs scale-to-zero on AWS.
Launch the live appA memory & deduction card game for 2–5 players, built into this site: room codes, realtime WebSocket play on Cloudflare Durable Objects, and a fully unit-tested rules engine. Grab friends, share a code, go lowest.
Play FoursightPrivacy-first Android app that reads bank SMS entirely on-device and turns them into three honest numbers — income, expenses, savings — with per-account reconciliation. TypeScript engine + Flutter port kept in lockstep by golden vectors. Raw messages never leave the phone.
Read the case studyFirst load takes ~1–2 minutes — the server sleeps when idle to keep it free, and wakes on demand.
