About

Building software that
people rely on.

I'm a Full Stack Developer specializing in React, Next.js, and Node.js — building production systems that scale. From designing reusable component libraries to architecting SEO-optimized pages serving thousands of users, I focus on delivering high-quality, maintainable code.

At Remitbee, I've independently led critical migrations, built greenfield applications, and shipped GraphQL services powering customer-facing products. I believe in pragmatic engineering — writing just enough abstraction, measuring real impact, and always shipping.
