Luxembourg
Summary
👤
SeniorGuillaume Hain is a seasoned software leader and entrepreneur based in Luxembourg with over 15 years of hands-on experience building and modernizing web applications, primarily in Ruby on Rails and JavaScript. He progressed from an autodidact C/C++/Python developer to leading teams and projects that serve hundreds of institutional clients, driving migrations, SOA splits, and scalable architectures. As founder and CEO of SANOUVA and former IT manager/team lead roles, he blends technical depth in containerization, microservices, Docker/Kubernetes and React/Angular with people management, code quality and testing disciplines. He has steered large Rails upgrades, extracted reusable libraries into gems, and introduced standard development practices across teams. Comfortable switching between backend, frontend and mobile (React Native), he’s equally focused on operational monitoring and production reliability as on new feature delivery. Colleagues describe him as a curious builder who moves from prototyping to production while coaching teams to adopt automated testing and modern deployment patterns.
