What I'm looking for

I seek senior backend or platform roles focused on scalable systems, cloud cost optimization, DevOps automation, and opportunities to mentor teams and solve complex engineering challenges.

I am a senior software developer with over a decade of experience building scalable backend systems, optimizing cloud costs, and delivering production-ready APIs and internal tools. I have led teams, architected high-performance ingestion and reporting pipelines, and saved companies tens of thousands annually through data-driven decisions and system improvements.

I enjoy solving hard problems across the stack—from .NET and Scala services to Dockerized CI/CD and cloud migrations—and continually learning new technologies, recently exploring game development in Godot while building an RPG in my free time.
