The person behind the work

Senior software engineer. Product builder. Systems thinker.

I work across product engineering, system design, real-time communication, and AI. The desk is equal parts engineering notebook and creative studio—because useful software needs both disciplined execution and a point of view.

What I do

I design and ship TypeScript-first products, real-time systems, and AI tools across frontend, backend, cloud, and product architecture.

How I work

I care about clear product decisions, dependable APIs, readable systems, and teams that can move confidently after launch.

Why this exists

This is a practical record of products shipped, systems built, lessons learned, and the problems I want to keep solving.
