About

Building systems that
don't break.

I'm a Lead Software Engineer with a decade of experience architecting secure, scalable applications for startups and enterprises alike. I specialize in full-stack TypeScript, cloud infrastructure, and building teams that ship with confidence.

Currently focused on distributed systems, developer tooling, and making security a first-class concern — not an afterthought.
