About

Full-stack engineer with a frontend center of gravity.

Seven-plus years of shipping product across web, hybrid, and native mobile. The bit I keep returning to: design-system contracts, performance work, and the unglamorous infrastructure that decides whether a team is actually fast.

Full-stack by practice, not by job title. I write the backend when the backend needs it, design APIs end-to-end, and have spent the last year wiring retrieval-augmented LLMs into real product flows — not chat demos. What I enjoy most is owning a feature from data layer to pixel, and being responsible for how it feels in the user's hand.

Outside the day job I tinker with hybrid app patterns, write about the frontend infrastructure that keeps teams shipping, and keep an eye on where AI-augmented surfaces are actually moving the needle.
