Message

At M-TEK (Pty) Ltd, I design control systems and develop embedded programs. I also wrote Python code for full-spectrum vector network analyser measurements and post-processing, and design electromagnetic slip rings and impedance-matching networks.

At CSIR Landward Systems, I designed and analysed electrical machines and other electromagnetic structures, including work involving electric and hydrogen-powered vehicles. Earlier, I designed four high-speed electrical machines and a low-speed micro-wind turbine at North-West University; four machines were manufactured.
