M.Sc. in Engineering, Robotics

Mälardalen University, Västerås

Studied robotics, embedded systems and artificial intelligence. For my master's thesis, I developed a radar-based hand gesture recognition system using Python, TensorFlow, and convolutional neural networks (CNNs). The system achieved 95% classification accuracy with a prediction time of approximately 25 ms.
