Summary
🤩
Rockstar🎓
Top SchoolSergey Morgunov is a pragmatic Java EE team leader based in Moscow with 11 years of experience building and leading backend teams for banking, advertising, and mobile server systems. He combines a strong applied-mathematics background and hands-on engineering discipline with proven leadership running Java EE development at AT Consulting. An active open-source contributor and software architect, Sergey has improved core features and CI/CD for high-profile JVM projects like Play Framework, play-json and Lagom, including WebSocket handling and serialization fixes for Oracle-backed JPA read sides. He brings DevOps sensibilities—modernizing build pipelines, GitHub Actions, and dependency management—so teams ship more reliably. Colleagues would describe him as pedantic and ambitious in the best sense: detail-oriented about correctness while pushing for practical improvements. Beyond day-to-day delivery, he has a track record of surfacing subtle cross-cutting issues (serialization, integration tests, CI) that often prevent production incidents.
