I currently work on the cutting edge of LiDAR development as one of the Principal engineers over Cepton Technology's LiDAR sensors, I develop innovative ways to increase LiDAR resolution and push the boundaries of LiDAR technology.I helped found Quilt-EZ in 2004 developing robotics for the textile industry. I have worked with brush-less dc motors creating custom space vector modulation controllers for variable speed and precision operations. I've created trajectory algorithms for tracking dual axis movements and developed a quality control program that tracks products through testing procedures and prevents shipping errors. I've managed finances, budgets, and human resources. I have detailed experience with Linux, networking, VOIP phone systems, servers, CAD, CAM, and multiple programming languages. I love learning new things and building from the ground up.
