Top SchoolSergei Korolev is a seasoned back-end developer and DevOps engineer with 12 years of experience building production services using Python, Node.js/TypeScript, Nix-based reproducible builds, Kubernetes, and Terraform on Google Cloud.

His background includes leading distributed IT teams in harsh, remote environments where he designed fault-tolerant networks and logistics-aware systems, a testament to his focus on reliability under constraints. An active open-source contributor, he has full-stack involvement in projects such as the XOD IDE, adding CLI tooling, tests and publishing workflows. Preferring remote work and a practical, safety-first approach to engineering, he cares about type safety, repeatable builds and delivering services that have real-world value.
