WHO I
AM

I'm a full-stack developer with a passion for building products that matter. I've spent 5 years shipping production code at companies ranging from pre-seed startups to Fortune 500s.

My approach is simple: understand the problem deeply, architect a clean solution, then execute with obsessive attention to detail — both in code quality and user experience.

When I'm not building, I'm contributing to open source, writing about web performance, or experimenting with generative art in Three.js.
