What I'm looking for

I’m looking for a role where I can own backend work end to end—designing PostgreSQL and API layers (GraphQL/REST), integrating secure third-party services, and shipping in small reversible steps with strong tests, observability, and CI-driven quality.

I’m a full-stack engineer with 7+ years building and running backend systems in TypeScript and Python on PostgreSQL over AWS and GCP. I’ve built backends that expose data through GraphQL and REST APIs, and I focus on owning technical work end to end—from reading existing code to covering it with tests and shipping changes in small, reversible steps.

My depth is in backend engineering: PostgreSQL schema and query design, GraphQL and REST APIs on top, and data validation and ETL pipelines that turn messy third-party financial input into reliable, regulated fintech data. I’ve decoupled live banking-integration layers with no downtime, built audited, least-privilege API access surfaces, and ensured production readiness with strong CI test coverage and security scanning.
