Alex Rothuis
Utrecht, Utrecht, Netherlands
Summary
👤
SeniorAlex Rothuis is a pragmatic software engineer with 11 years of experience building maintainable, testable systems and guiding teams toward sound architectures and pragmatic testing strategies. Based in Utrecht, he blends hands-on backend work—contributing to the Gleam standard library—with consultancy and coaching roles that improve development practices, CI/CD, and long-term maintainability. His background as an IT lecturer and curriculum designer informs a strong emphasis on software quality, architecture patterns (hexagonal, DDD, CQRS), and modern testing approaches like property-based testing and mutation tests. Alex has applied this expertise across media platforms, enterprise content systems, and retail promotion domains, often as a freelancer who both architects solutions and levels up teams. He also holds cum laude legal training in Law & ICT, a less obvious asset that strengthens his approach to security, privacy and compliance when designing systems.
