What I'm looking for

I seek a role where I can lead backend and real-time system design, own end-to-end features, and improve reliability and performance within collaborative, product-focused teams that value observability, secure integrations, and rapid iteration.

I am a Staff Software Engineer with over 10 years building and scaling production systems across marketplace and healthcare domains, specializing in backend architecture, real-time data pipelines, and distributed systems. I own features end-to-end, ship quickly, and improve performance, reliability, and UX at scale through cloud-native engineering, observability, and secure integrations.

At Amazon I led core contributions for Local Selling, built high‑throughput inventory sync pipelines, optimized microservices in Go and Java, and delivered frontend improvements with React/Next.js to accelerate seller onboarding. Previously at Doxy.me I implemented HIPAA-compliant WebRTC solutions, integrations with HL7/FHIR and DICOM, and migration to microservices and CI/CD, improving reliability, throughput, and operational velocity.
