Summary
🤩
Rockstar🎓
Top SchoolMichal Maciejewski is a seasoned engineer and researcher with 15 years of experience specializing in electric vehicle fleet optimization, transport simulation, and vehicle routing. He combines academic depth (PhD in vehicle dynamics) and industry impact, currently leading EV fleet optimization at Einride while holding a senior scientist role at TU Berlin. Michal is a hands-on Java developer and open-source contributor to prominent projects like MATSim and jsprit, where he focused on refactoring and performance improvements for detour/path and routing computations. His work bridges simulation, AI/ML, and GIS-enabled routing for e-mobility and autonomous systems, often improving accuracy of travel time and detour calculations that underpin real-world dispatching. Based in Greater Poland, he brings a rare mix of vehicle-dynamics insight and scalable backend engineering to complex mobility problems.
