Kirsch Mackey

Kirsch Mackey is an electrical engineer, educator, and content creator with over 15 years of experience spanning power systems, control systems, electrical systems, embedded programming, PCB design, power electronics, and high-speed digital systems. As founder of HaSofu and former adjunct professor, he developed the MESH method—a structured approach to high-speed PCB design that has helped students land roles at companies like Apple, Intel, Cisco, Garmin and Amazon in months rather than years. Drawing from industry experience at Intel and beyond, Kirsch bridges theory and practice through technical writing, courses, and hands-on workshops that make complex engineering concepts accessible and actionable.
