$ cat about.md

I've been writing software professionally for 15 years, and I still get genuinely excited when a hard problem lands on my desk. That curiosity is probably the thing that defines me most as a developer — more than any language or framework on my resume.

For the past several years I've been building full-stack systems at SAP Concur, working primarily in Go and TypeScript/React — greenfield features, security hardening, legacy migrations, and everything in between.

I'm drawn to smaller teams because I like being close to the work and the people. I'm a self-taught developer at heart: I'm used to figuring things out, and I never really stop learning.
