I started my career designing and evaluating automotive analog semiconductor circuits, specifically power ICs. Later, I shifted my focus to analog circuits for measurement, working on the design and manufacturing of inspection and experimental equipment for machinery manufacturers.With a broad range of experience, including designing small-scale measurement analog circuits and FA-related control panels, I have also utilized simulation tools like finite element analysis software and power electronics simulation tools.Currently, I leverage this diverse expertise to offer development contracting and technical support services.
