Top SchoolSebastian Feduniak is a pragmatic software engineer and consultant with about a decade of experience designing, building, and testing large-scale, highly available multiregional systems.

Comfortable across the full stack and operations, he brings production-focused expertise in databases, observability and CI/CD to complex projects.
