I am a System Engineer, working and developing new Medical Devices. Before that, I worked as an Application Engineer focusing on The MathWorks Physical Modelling and Control Design Product lines. I consulted different companies during the evaluation and development stages of their projects. I had tight cooperation with the marketing and sales team, and conducted a Technical Seminar every few months. I also used to teach Simulink and Stateflow to MathWorks customers, so if you want to learn something - just ask. Professional Interests: Control Design, Physical Modeling, Code Generation, Embedded Systems
