I've finished my M.Sc in Computer Science in the field of Computational Geometry. My first experience with simulations was already back then - part of my thesis involved building a GNSS-Signals simulator. Deploying some novel optimizations, we improved performance dramatically.
Since then, I've worked as a software engineer in different roles with vast experience in Python. My last one, arrived at early stage to a fast-growing startup named Fabric (CommonSense Robotics) and involved in the system architecture and development, which a simulation is a crucial part of it.
