About

I gravitate toward the parts of software that decide whether a product holds up — clean data models, well-drawn service boundaries, performance, and the tests that keep it honest. I like going deep on a problem, shipping something real, then sharpening it. Most of my work lives in backend and distributed systems, and I care about code that stays simple as it scales. If you're building something that has to be reliable under load, I'd love to connect.
