Space
Developed and documented a satellite thruster controller using full VHDL design without schematic capture. The project included conducting detailed power, loading, and timing analyses to meet the ultra-high reliability standards required for space flight.
Defense
Designed and analyzed specialized switching power supplies used to drive lasers over a wide variety of power levels for military and law enforcement applications.
Medical Devices
Performed exhaustive worst-case analyses on digital, analog, linear, and switching power supplies, alongside loading, timing, power dissipation, and FPGA Verilog code assessments, introducing vital design improvements for medical instruments.
Telecommunications
Engineered an I/O-intensive controller board supporting multiple communication modes and an IEEE interface. The design was updated from the Motorola MC68360 processor to the more powerful MPC860 to meet enhanced performance and speed requirements.
