Summary
🤩
Rockstar🎓
Top SchoolEwout Hoeven is a scientific researcher and data-driven policy analyst with a decade of experience building and maintaining open-source tools for agent-based modelling, mobility research, and geospatial analysis. Based in Delft, he combines academic training in engineering and policy analysis from TU Delft with hands-on engineering across projects like Mesa (core maintainer) and OSMnx, where he optimized core graph routines for performance. His work spans backend development, DevOps automation, and CI/CD maintenance—improving build pipelines for projects such as AliceVision and libavif and modernizing Cython for Python 3. A strong communicator and educator, he has taught and mentored students at TU Delft while shaping Mesa release cadences and community engagement. Ewout’s profile blends policy insight with pragmatic software craftsmanship, making him adept at turning complex mobility questions into reproducible simulations and robust tooling. Notably, his contributions often focus on performance-sensitive refactors and build-system reliability that quietly uplift large scientific codebases.
