Summary
🤩
Rockstar🎓
Top SchoolPatrick Mogensen is a Senior Product Engineer based in Copenhagen with 11 years of experience building reliable backend systems, test automation, and scientific software for the pharma and research sectors. He blends deep quantitative training (MSc in Economics and a PhD-level background in structural dynamic models) with hands-on engineering, contributing to core Julia projects including JuliaLang/julia and the widely used HARK economics toolkit. At Julia Computing and now PumasAI he helped productize clinical trial simulation and modeling pipelines, translating research-grade algorithms into production-ready stacks. His open-source work spans optimization, plotting, and numerical libraries—improving test coverage, implementing hessians and line-search enhancements, and adding plotting backends—showing a focus on correctness and reproducibility. Colleagues know him for catching subtle numerical issues (e.g., Rational rounding and interpolation edge cases) and for bridging academic rigor with pragmatic product delivery.
