Professional Summary
A resourceful engineer who looks to take the initiative. I am adept at developing original solutions but always happy to consider outside perspectives and build toward external ideas. Strong communicator and team player with a proven track record in each layer of embedded systems engineering from circuits, to UI's, and all the software architecture in-between.
Experience
Embedded Software Engineer
Cellectric BioSciences | 2023 – Present (2 years)
- Circuit Design: Designed and manufactured ESP32 architecture based circuits targeting the control of hardware such as stepper/solenoid drivers and I2C/SPI sensors.
- Firmware, RTOS & RPC Implementation: Created C++ firmware with Real-Time Operating Systems and RPC frameworks.
- GUI & Control Software: Built a cross-platform GUI (Qt) and Python3 application following OOP, MVC, and event-driven design patterns to ensure thread safety and modularity.
- DevOps & CI/CD: Established CI/CD pipelines, Docker containers, and packaging processes to streamline development and deployment.
- Microfluidic System: Designed a microfluidic subsystem integrating peristaltic and syringe pumps, solenoid valves, and sensor feedback (temperature, pressure, flow rate).
Mechatronic Engineer
BlackGold.Earth | 2021 – 2022 (4 months)
- Sustainable Systems: Designed a modular micro-farm container facility.
- Geospatial Software: Collaborated on a proprietary satellite imagery solution for produce tracking.
Notable Projects
Pressure-Driven Flow Controller
- Designed the circuit board to drive four piezoelectric micro-pumps. The circuit consisted of several H-Bridges, voltage boosters, current sensing op amps, I2C interfaces, and an embedded ESP32.
- Developed and programmed RTOS-based firmware for ESP32 microcontroller, incorporating a PID control algorithm to regulate flow-rates and ensure precise device control in real-time environments.
- Notably, the system is equipped with current sensing capabilities to allow frequency tracking, improving system performance and lifecycle.
Honors Thesis [Cum-Laude]
- Designed and developed a heating vest prototype realized through a novel conductive heating fabric.
- The project’s successful completion strengthened my knowledge of digital control design, C++, OOP principles, and sensor implementation and integration.
Key Achievements
- Medical Device Completion: I am proud to say that the device developed at Cellectric from the ground up is undergoing hospital based trials as well as research use with several universities, laboratories, and international BioTech companies.
- Award-Winning Thesis: My thesis (80%) was nominated for the Stellenbosch University Innovation Award and placed as the second runner-up among seven finalists selected from over 700 candidates.
