About Me

I engineer robust backend solutions that power enterprise-grade applications. With a strict focus on performance and data consistency, I build systems that scale effortlessly to millions of requests.

My experience spans from designing event-driven architectures with queues to optimizing database queries for sub-millisecond latency. I value pragmatic code that is easy to maintain and deploy.
