About me
I am a Senior Electronic & Mechatronic Engineer (M.Eng First Class) with extensive R&D experience in Automotive, Industrial IoT, and Power Electronics. I specialize in designing "Full-Cycle" hardware solutions—taking projects from initial concept and simulation to PCB layout, firmware development, and mass production (DFM).
My background involves engineering critical systems where failure is not an option. From designing 1kW Electronic Loads to architecting 100,000-node IoT networks, I ensure every board I design is robust, compliant, and cost-optimized.
