About
Engineering with clarity and ownership.
I help teams ship reliable backend platforms by combining thoughtful system design with hands-on delivery. My focus is on services that stay fast, observable, and maintainable at scale: consistent REST APIs, clear domain boundaries, production-grade data flows, and integrations that can be operated with confidence.
From enterprise retail platforms to personal Cloud Run products like TriedTables, I work across backend design, third-party APIs, OAuth security, Firestore persistence, deployment automation, metrics, dashboards, and production support.
