Hardware development | Mentor (Siemens, PADS), OrCad, Autodesk

PROFILE Since childhood, I have been passionate about physics and electronics. During high school, I focused on audio electronics and tube amplifiers. Combined with my love for music, this passion for electronics grew stronger. I studied schematics, layouts, and EMC principles, repaired numerous audio devices (such as mixing consoles and amplifiers), and even designed and built a studioquality analog audio crossover for measurement purposes - featuring high dynamic range, low distortion, and complete panel design and mechanical realization. With over 6 years of experience at ZF and more than 15 years in electronics overall, I have gained comprehensive knowledge of the entire product development process - from initial concept through design, optimization, programming, and testing, all the way to serial production. Today, I aim to further develop my skills and, leveraging my engineering background, progress toward a team leader role.
