Rockstar🎓
Top SchoolPaul Hampson is a seasoned software engineer with 19 years' experience specializing in backend systems, containers, and Windows internals, now based in Shibuya, Japan. He has contributed significant fixes and features to high-profile open-source projects like Moby, containerd, and Microsoft's hcsshim and go-winio libraries, improving Windows container builds, large-file handling, and debugging utilities. At Wargaming he progressed from senior coder to principal architect and product owner, blending hands-on engineering with product leadership across game backends and microservices. Paul pairs deep systems-level knowledge—demonstrated by low-level container and filesystem work—with pragmatic DevOps and CI/CD improvements that keep complex builds and tests reliable. Fluent in multiple languages and formally trained in Japanese and Vietnamese, he brings cross-cultural communication and longevity working across remote and distributed teams. He’s equally comfortable refactoring build tooling like CMake and improving test infrastructure as shipping production services.
