  As the main electrical engineer and circuit designer, I create analog / digital / mixed PCB designs and specifications for various PCBs contained within high-precision medical devices. The PCBs control a variety of tasks within the device, including pressure and temperature sensing, motor driving, and power regulation and management. I also serve as the team's lead firmware developer for the system controllers, handling on-controller data processing and feedback algorithms to control hardware. I manage internal controller communication through a custom serial protocol interface I created for system integration. I have authored comprehensive use-documents for hardware setup and the firmware communication protocol. Show less

  • Oct 2017 - May 2020

  As an electrical engineer, I was involved in our PCB design cycle from the ground up, from design all the way to manufacturing exports. Designs included solenoid current management, LED array control, and optical detection modules I was also involved in firmware maintenance and upkeep, as well as active development of firmware for new hardware PCB prototypes. Main firmware tasks included updating the internal serial protocol for new commands, analog and digital sensing, and inter-board communications. As a software engineer, I developed software applications / GUIs for hardware testing and new system prototypes, and was the lead designer of a C# application for an RF prototype and a python application for RPi hardware interface testing.
