Engineer, end to end.

Software engineer with full-stack and backend experience shipping healthcare data platforms, booking systems, and ML pipelines. Duke Computer Science graduate (AI & ML) who owns features end-to-end — from PostgreSQL schema and REST API to the React UI on top.

I care about the parts users never see as much as the parts they do — schema design, API contracts, auth flows, caching — and the interfaces that sit on top of them. From healthcare data platforms to booking systems to ML pipelines, I take products from idea to production and keep them reliable once they're there.
