What I'm looking for

I seek backend or full‑stack roles at collaborative, product‑driven teams where I can build scalable, testable systems, improve observability, and lead modernization efforts while continuing to grow in cloud and architecture responsibilities.

I am a full‑stack software engineer with experience designing and modernizing backend systems for high‑traffic applications, migrating legacy infrastructure to AWS, and building microservices in Django and .NET. I have delivered measurable improvements—reducing query latency, cutting redundant API calls by 20%, and increasing test coverage by 30%—while collaborating cross‑functionally to deploy reliable production services.

I thrive in Agile teams, contribute to architecture and observability efforts, and write pragmatic automation and scripts to speed debugging and deployments. My background spans Java, Python, C#, React, databases, containerization, and cloud platforms, and I focus on maintainable, testable code that scales with business needs.
