Summary
🤩
Rockstar🎓
Top SchoolFons Van Der Plas is an educational development officer and software engineer with 11 years of experience blending teaching, tooling and open-source development. He helped design interactive learning environments like Pluto.jl at MIT and contributes to core Julia projects—improving modules such as Markdown, Base64, Dates and the REPL—bringing production-quality fixes, tests and documentation. His background in mathematics and hands-on teaching (Radboud University) informs a user-focused approach to developer tooling and autograding for computational courses. At JuliaWeb he strengthened HTTP and WebSocket reliability through targeted bug fixes and expanded test coverage, demonstrating care for interoperability and robustness. Now based in Wageningen and recently transitioning into educational development at Eindhoven University of Technology, he combines classroom experience with low-level backend contributions. An unexpected thread through his profile is ongoing curiosity beyond software—he has pursued vocational tree-worker training, reflecting practical problem-solving outside the codebase.
