Senior🎓
Top SchoolFabien Rozar is a versatile software engineer and entrepreneur with 11 years of experience blending scientific computing, 3D visualization, and startup product development. He holds a PhD in computer science and has applied HPC and parallelization techniques to scientific simulators while later focusing on point cloud processing, UI/visualization, and cloud toolchains in C++ projects. As co-founder of Flaxib he translated technical expertise into transport-focused digital twins and on-demand mobility software, and he continues to work independently to deepen his Clojure and functional-programming skills. An active open-source contributor, he improved 3D camera controls in the widely used manim animation engine and modernized Qt-based visualization tutorials in the Point Cloud Library, showing a knack for bridging research-grade code and practical developer tooling. Based in Lyon with roots in Réunion, he pairs rigorous academic training with hands-on delivery across research labs, startups, and training roles.
