Selected Projects
FormHook
Built a high-throughput event intake and webhook delivery system with guaranteed retry logic, so frontend teams can fire events without writing backend glue code for delivery, retries, or failure handling. Handles concurrent API loads and gives developers a single endpoint instead of building queue infrastructure from scratch.

Form Backend
PinPoint
Built a real-time GPS tracking engine for logistics, syncing driver and customer views through Firebase's realtime database with anonymous authentication. Chose polling over WebSockets deliberately — a 1.5 to 2 second sync interval that's simple to debug and reliable at this scale. Routes calculate through OSRM for real road paths, with automatic rerouting once a driver drifts past 300 meters off course.

Live Tracking
ClosetAI
Built an AI-powered outfit recommendation engine using Ministral 3 14B Instruct, a genuinely multimodal model served through NVIDIA NIM, handling both image understanding and structured attribute extraction in a single call. Backend runs a three-tier ranking fallback — full AI ranking, a lighter ML model once a user has real feedback history, and rule-based scoring underneath both — so the system always returns a usable result even when the top tier isn't available.
