What I'm looking for

I'm looking to build reliable backend and data-platform products in regulated domains, with end-to-end ownership in remote, cross-functional teams.

I've built production systems for Medidata's clinical data platform and Fintiba's blocked-account platform, delivering Python/gRPC data services, client SDKs, payment workflows, and release engineering in regulated environments.

At Medidata, I moved row-quality metrics into an Apache Arrow Flight server, removed 300+ lines of legacy R SDK logic, stabilized gRPC error handling, and delivered a migration for 822 orphaned records in 9 seconds. Earlier, I bootstrapped SpotOn's merchant onboarding backend from Figma designs, built Django REST APIs and React components, and configured AWS services for uploads, monitoring, and secrets management.
