Summary
👤
Senior🎓
Top SchoolHerbert Crepaz is a technical lead with nine years of engineering experience who bridges advanced experimental physics and high-precision industrial software for semiconductor lithography. He leads Matlab/Simulink/Stateflow model-based development and diagnostics for ASML DUV/EUV machines, driving simulation and embedded solutions for reticle stage measurement in high-NA systems. Previously he delivered ultra-sensitive atomic magnetometry and atomtronics research at top labs (Oxford, CQT, NTU), work that earned an Ig Nobel and publications in Scientific Reports, reflecting a rare blend of hands-on lab instrumentation and control-software expertise. Herbert contributes to open-source rendering tooling—adding shaders and quality fixes to appleseed’s 3ds Max integration—demonstrating practical back-end skills beyond his primary domain. Based in Sofia, he combines rigorous scientific training (PhD in quantum optics) with product-focused systems engineering and cross-disciplinary communication.
