About

bio.md

I'm a product-oriented software engineer with 9+ years shipping production systems across fintech, e-commerce, logistics, healthcare, and AI-native platforms. I focus on backend work: Node, NestJS, Postgres, and AWS — with strong hands-on depth in React, Next.js, and React Native.

I own architecture decisions end-to-end and thrive in environments where speed and quality matter equally. I work best cross-functionally, where technical decisions stay aligned with product and design.
