Top School

Arnold Metselaar is an experienced software engineer with 20 years of practice bridging rigorous mathematics and production C++ systems, holding a PhD in Mathematics from the University of Twente. He has applied his deep knowledge of numerical methods and physics to modeling and simulation projects in dredging and rail domains, and contributed parsing and grammar improvements to the SonarQube C++ community plugin. Comfortable writing robust back-end code and test suites, Arnold increasingly aims to pivot from “software engineer with physics knowledge” to “physicist with software fluency,” seeking roles that emphasize underlying physical models and mathematical analysis. His background includes academic research on wavelet theory and hands-on SCRUM development for industrial simulators, reflecting both theoretical depth and pragmatic engineering. Based in Vinkeveen, Netherlands, he brings a rare mix of doctoral-level math, long-term C++ expertise, and a curiosity for non-obvious language and parsing intricacies.
