What I'm looking for

I seek senior backend or full‑stack roles where I can design scalable systems, own database reliability, lead and mentor teams, and deliver measurable performance and cost improvements using Go, PostgreSQL, ClickHouse and modern CI/CD.

I am a senior software developer with extensive backend and full‑stack experience, specializing in Go, PostgreSQL, ClickHouse and scalable distributed systems. I have led teams and delivered measurable performance improvements, including reducing OLAP processing from days to minutes and improving sync times from minutes to seconds.

I publish technical writing, train developer teams, and contribute to open source while solving database and infrastructure problems. I am driven to architect reliable, testable systems, mentor engineers, and own end-to-end product and platform outcomes.
