Summary
👤
Senior🎓
Top SchoolSimon Van Casteren is a software architect with 12 years of hands-on experience designing and simplifying complex systems, from distributed microservices and type-safe full‑stack TypeScript to Rust firmware for ESP32 devices. He favors minimalist, iterative delivery—shipping the smallest useful iteration and evolving architecture as domain knowledge grows—to boost development velocity and reduce support overhead. His work spans database design (PostgreSQL), centralized servers, custom embedded hardware, and multiple user interfaces, with an emphasis on strong typing, functional principles, and pragmatic automated testing. An active open-source contributor, he improved the Oni Neovim-based editor’s UI and type safety, reflecting a habit of improving developer ergonomics as well as user experience. Based in Belgium and trained at KU Leuven, he combines technical depth with business-focused analysis to turn legacy complexity into lean, maintainable products.
