Senior Backend Engineer with 6+ years of experience building B2B, financial, and multi-tenant systems. My work focuses on backend architecture, PostgreSQL performance, concurrency and race conditions, observability, and production reliability.
Recently, I optimized a critical monolithic workflow and reduced its P95 latency by 50%. I have also maintained APIs serving more than 1 million monthly requests with a server-error rate below 0.004%.
I am looking for a remote Senior Backend Engineer or Backend Platform role, preferably through a B2B/contractor arrangement. I value teams with clear architectural ownership, rigorous code reviews, direct communication, and a pragmatic approach to building reliable software.
