Work

5 roles, newest first, from immersion cooling in Austin back to the validation benches in Dallas where it started.

History

Nov 2025 - Present Full-time Austin, Texas, hybrid

The controls for data center immersion cooling, where the servers sit in a tank of dielectric fluid instead of a stream of air.

Supported electrical integration, wiring, bring-up, and debugging of Nano, NX Rack, and Atto liquid-cooling platforms
Developed OpenPLC logic for temperature loops, alarms, interlocks, sensors, and system control
Supported and coordinated NEMKO validation, including test preparation, troubleshooting, hardware changes, and follow-up
Designed LED and stepper interface PCBs, including schematic capture, component selection, layout, bring-up, and iteration
Developed stepper motor control firmware and integrated drivers, home/limit sensors, and communication interfaces
Performed PCB soldering, rework, wiring changes, and rapid hardware modifications during development and validation
Designed cable and harness integrity test setups and supported harness design, fabrication, assembly, and manufacturing
Developed Linux-based UI, terminal utilities, and services for system configuration, monitoring, control, and operation
Developed and debugged RS-485, CAN, I²C, and USB communications across controllers, sensors, actuators, and peripherals
Created test procedures, validation plans, wiring diagrams, assembly instructions, troubleshooting guides, and product manuals
Created 3D CAD and PCB/mechanical integration models for documentation, fitment, manufacturing, and system integration
Worked with vendors to evaluate components and subsystems, identify improvements, assess tradeoffs, and analyze cost

Jun 2022 - May 2023, Jan 2025 - Jul 2025 Contract Richardson, Texas, on-site

The heater and charger around a radar product’s battery, from the control loop on the Nucleo through to the documents the factory builds from.

Designed and implemented a solar-powered battery heater using a PID control loop on an STM32 Nucleo board, holding LiFePO4 cell temperature in sub -30 °C conditions.
Developed and tested custom DC-DC buck control logic, MPPT tracking, and battery charging algorithms tuned for cold weather.
Wrote firmware in STM32CubeIDE and deployed it to embedded hardware inside a commercial radar product.
Ran GPS and 4G validation with tools like VisualGPS, and tuned antenna performance for radar-to-GPS synchronization.
Led solar chamber testing by building an artificial freeze environment to simulate low-light, low-temperature conditions.
Worked across design, firmware, test, and in-house manufacturing to iterate PCB layouts in Siemens PADS and KiCad and improve design-for-manufacturing readiness.
Wrote the technical documentation for internal manufacturing and outside production partners, and supported regression testing and post-market monitoring of deployed units.

Jan 2024 - Dec 2024 Contract Plano, Texas, hybrid

Prototype IoT and battery hardware for medical devices, and the Python tools that tested it on the bench.

Prototyped IoT devices in Python and C++, including an AQI measuring device and a TI BQ battery IC control device.
Wrote embedded firmware in C++ for STM-based systems and integrated it with custom hardware for end-to-end validation.
Validated motherboards on the bench with oscilloscopes, DMMs, and a range of power supplies, and used an automated test fixture to speed up debugging.
Built test scripts with Python, OS libraries, and Tera Term macros, and a Windows data-acquisition app in Tkinter, PyQt5, and MCCULW.
Designed a four-layer RF board for LTE communication in Altium Designer, and ran the hardware bring-up and debugging.
Automated document and workflow management with Python, and ran offline ML models for documentation and analysis.
Authored regulatory documentation for medical devices.

Jun 2023 - Sep 2023 Full-time Torrance, California, on-site

A thermal test bench for an EV program, automated so a whole set of ECU scenarios could run without anyone rewiring in between.

Designed a hardware-in-the-loop system to automate thermal test bench testing using relays, NI DAQ, CANoe, and ECU Test, covering every scenario without manual setup.
Built flexible test benches able to simulate complex ECU scenarios with automated switching logic.
Documented the HIL design method so the approach stayed consistent and debuggable across the team.
Worked with the firmware and thermal systems teams to widen test coverage and cut regression time.

Jul 2021 - Dec 2021 Full-time Dallas, Texas, on-site

Testing infotainment systems on the bench and in the car, and writing the Python that kept the tickets straight.

Ran vehicle and bench testing for automotive infotainment systems, logging bugs in Jira and doing the root-cause analysis.
Flashed experimental firmware to main and sub microcontrollers for feature verification and debug.
Logged and analyzed system data over CANoe, serial interfaces, and PuTTY for both software and hardware validation.
Retrofitted next-generation infotainment components into test vehicles for field evaluation.
Wrote Python scripts to automate ticket tracking and reporting, and coordinated Jira workflows across QA and engineering.
Stripped and rebuilt complex electronics for diagnosis, soldering components through the rework phases.
