About Me

Clear thinking. Scalable systems.

Principal Full-Stack Architect with 10+ years designing scalable platforms across healthcare, fintech, and logistics. I own architecture end-to-end, from system design and API contracts to cloud infrastructure and production delivery, making the technical decisions that keep systems fast, reliable, and easy to evolve. I've shipped AI-powered products from concept to production, automated credentialing pipelines that cut processing time by 99%, and modernized legacy systems without a single service disruption.
