David Perna is a Electrical Engineer II at Microsoft. He possess expertise in digital circuit design, pcb design, schematic capture, altium designer, c and 15 more skills. Colleagues describe him as "I would frequently run across David working late nights in the office and garnering sympathy from passing coworkers. Burning the midnight oil paid off though since he’s delivered impressive engineering projects beyond his years such as a full Qualcomm SoC board design from scratch, restoration of the first electron scanning microscope, and a custom electromechanical automated test jig - as a true T shaped engineer I won’t hesitate to call on David should we ever find the next great startup idea!" and "David is a man you can trust to do a high quality job in a short amount of time. Working on a team with David was a pleasure, as we could always trust him to think of a genius solution to a difficult problem. If you need an outside-of-the-box thinker who can deliver unique solutions in a short period of time, give this guy a call!"
