About

Turning complex, ambiguous problems into production-grade distributed systems.

I'm a Senior Full-Stack Engineer with 8+ years architecting and shipping production systems for fintech and global workforce platforms. My background spans event-driven microservices in Node.js, NestJS, and Laravel; React and Next.js on the front end; and the AWS / Docker / CI-CD layer that gets everything reliably into production. I care deeply about system design, TDD, observability, and raising the engineering bar on every team I join — currently serving as Engineering Lead at Tech1M while experimenting product ideas on the side.
