About

I'm a fullstack engineer who likes shipping systems that quietly do a lot of work. I've built a marketplace with a Gemini-powered no-code site builder, a WhatsApp-class messaging platform on Meta's Cloud API, and an autonomous SEO engine that took ~80% of the manual editorial work off a team's plate.

I care about the boring parts — latency, correctness, and code that's still legible six months later.
