  • Participate in weekly meetings to discuss language and standard library design and implementation

Universal Flash Storage Support for LumenX Platform

  • Led development of UFS support for LumenX programming platform
  • Contributed to Lattice FPGA gateware converting parallel bus designed for eMMC to UFS serial interface
  • Implemented software interface to Lattice FPGA gateware
  • Contributed to Xilinx FPGA gateware modifications to increase parallel bus speed from 50 MHz DDR to 200 MHz SDR, doubling throughput

Glasgow Interface Explorer

  • Designed ADC circuit to sense external voltage and DAC circuit to control output voltage of adjustable voltage regulator
  • Contributed to layout of Rev B PCB, including fixing signal integrity and EMI issues with direction-sensing level shifters
  • Contributed to design of Rev C PCB, including redesigning I/O cell to use individually direction-controlled level shifters

LLVM MSP430 Backend Improvements

  • Converted LLVM's MSP430 backend to comply with the published EABI from Texas Instruments
  • Implemented support for returning structures larger than 64 bits from functions
  • Worked with community leaders to add these modifications to the fork of LLVM used by the Rust programming language
  • Served as a member of the MSP430 team of the Rust embedded organization

Elysium VHF/UHF Radio

  • Designed and developed a full-duplex VHF/UHF transceiver for the CubeSat nanosatellite market
