What I'm looking for

I seek senior engineering roles building secure, reliable full-stack or distributed systems, with strong emphasis on observability, CI/CD, mentorship, and measurable product impact.

I am a senior software engineer with deep experience building patient-facing healthcare features and globally distributed storage systems. I combine strong full-stack skills in TypeScript/React/Node with backend expertise in Java and Python to deliver reliable, secure products.

At Color I helped design HIPAA-aware APIs and operational practices, added observability and SLOs, and improved release safety through contract tests and canary deployments. Previously at Amazon I optimized distributed storage and database services for durability, availability, and low latency while reducing operational load and improving failure isolation.

I lead technical delivery end-to-end, define architecture and CI/CD practices, and mentor engineers to ship high-quality software. I prioritize security, reliability, and measurable product outcomes when aligning engineering work with business and user needs.
