What I'm looking for

I seek a role where I can own end-to-end systems, solve distributed-systems and performance challenges, and ship reliable production services within a collaborative, operations-minded team.

I am a Senior Full Stack engineer with 10 years of experience building high-trust systems using Golang and Python alongside polished React and TypeScript front ends. I have delivered end-to-end fintech and healthcare products, designing clean APIs, async workflows, and well-tuned PostgreSQL models.

I focus on practical, production-ready engineering—performance, reliability, and strong ownership—taking features from idea to launch on AWS and Kubernetes and keeping them healthy after release. My work includes backend microservices, event-driven transaction systems, reconciliation jobs, and internal admin dashboards that reduce manual work.

Among my achievements are architecting internal ledger systems, optimizing Postgres schemas and indexing for financial queries, integrating Redis caching to improve response times, and establishing monitoring and observability standards. I enjoy solving distributed-systems challenges and shipping dependable software that teams can rely on.
