Summary
🤩
Rockstar🎓
Top SchoolBenny Bottema is a Frontend Architect with 17 years of hands-on experience modernizing complex enterprise frontends and backends across Dutch public and financial institutions. Based in Leeuwarden, he drives architectural consolidation—introducing monorepos, reusable portal-style components, CI/CD enforcement and measurable quality gates using ESLint, Sonar and Fortify—to accelerate legacy-to-Angular migrations. Equally at home in Java and Angular ecosystems, he has improved both server-side tooling and CLI usability through open-source contributions to projects like Simple Java Mail and the popular picocli framework. His background blends full-stack delivery, DevOps practices (Kubernetes, Jenkins, Prometheus) and system testing with Cucumber, giving him a pragmatic focus on operability and risk controls. As a freelance consultant and team coach he repeatedly standardizes development practices, from microservice patterns to release management, helping large organizations reduce technical debt. Notably, he pairs architectural vision with code-level fixes—resolving lint backlogs and adding unit-tested CLI features—so strategy translates into shipped improvements.
