About

I'm a full stack software engineer with 5+ years of experience shipping production systems across fintech, education, and enterprise software. My backend depth is in C#/.NET, Node.js, and Golang; on the frontend I work primarily in Next.js, React, and TypeScript.

I've led development teams and mentored engineers — from code review and architecture decisions to pairing junior developers through their first production incidents. I care about systems that stay boring in production: clear boundaries, sane data models, and observability that tells you what broke before a user has to.
