Summary
🤩
RockstarMatthijs Cox is a Metrology Architect at ASML with nine years of experience bridging physics, software engineering and data science to deliver high-value algorithmic products for nanometer-scale lithography. He spearheads adoption of modern numerical tooling—most notably driving an inner-source Julia ecosystem of 100+ packages—and focuses on developer experience, CI/CD and cross-platform deployment to accelerate engineering outcomes. With a PhD-trained physics background and hands-on experience across Python, R, MATLAB, C/C++ and Julia, he uniquely translates scientific problems into production-ready software and scalable roadmaps. Matthijs is an open-source contributor (Julia bindings for the popular BrainFlow biosensor library), community organizer for JuliaLang Eindhoven, and a founder-minded technologist who also explores neurotechnology and bionic control systems. Colleagues know him for combining systems thinking with clear communication and a knack for making complex, multi-stakeholder projects practical and fast.
