Summary

Rockstar🎓
Top SchoolStefan Harr is a Senior Software Engineer based in Luleå, Sweden with 14 years of experience building web-first systems and interactive physics simulations. He blends a strong academic background in engineering physics with hands-on full-stack practice—PHP, Node.js, MySQL and modern cloud PaaS—gained through roles in research labs, startups, and long-term work at Star Stable Entertainment. Stefan focuses on numerical and mathematical problems in co-simulation and browser-based physics, applying WebGL, HTML5 and FMI to bridge research-grade simulation with production web apps. As a self-employed developer he moved from self-hosted LAMP to scalable Node.js cloud deployments, and he continues to ship creative web projects in his spare time. Familiar with server maintenance, solver analysis and optimization, he’s equally comfortable tuning low-level simulation solvers as crafting user-facing web experiences.
