I don't just write about building things. I build them. Here's what taught me everything — with the code.
BLE-based positioning for shopping malls. Changi Airport style. Under 2m accuracy across 50,000 ft². Deployed at GraspIO, Bengaluru.
Applied mathematics meets hardware. Kalman filtering — same technique self-driving cars and LLMs use for prediction. Signal processing, probability, real-time systems.
Two-way Google Calendar integration at WokayHQ. 10k DAU. Cut scheduling time 60%. Conflict resolution, recurring events, timezone handling, offline queueing.
Calendar systems are deceptively hard. Time is a distributed systems problem. Getting this right at scale teaches real distributed thinking.
High-reliability sync for WokayHQ's task manager. 45% uplift in task completion. CRDT-inspired conflict resolution. Works on 2G in rural India.
Most of the world doesn't have reliable internet. Designing for offline-first isn't a feature — it's architecture.
End-to-end system at Littlebird.ai. Swift screen-recorder → Whisper live transcription → React/Electron UI. LLM agents auto-summarise within 60 seconds.
Real-time AI integration — not a demo, a shipped product. Speech-to-text, NLP, agent orchestration, desktop apps. All in one system.
Multi-purpose language designed to be fast and easy. Arena-allocated. Compiles to Zig. Lexer, parser, type checker, and code generator built from scratch.
Building a language teaches you the stack from silicon to syntax. This is why I can debug problems others can't find.
