About Me

The mind
behind the
keyboard.

Hey — I'm Alex Chen, a developer at the intersection of engineering precision and design intuition. I believe the best software is invisible; it just works, beautifully.

Over 5+ years I've shipped production systems for startups and enterprises — from real-time trading platforms to AI-powered creative tools. My craft spans full-stack architecture, performance engineering, and UI systems.

I care deeply about the details — the spacing that makes a layout breathe, the 12ms that separates smooth from jarring.
