WORK

In this section, I provide a summary of my work history, with some sections broken out into dedicated pages for more detail.

While in school, I worked three semesters as a co-op at Southern States, a high-voltage switchgear manufacturer. While there, I designed, built, and tested high-voltage switchgear, including capacitor- and reactor-switching devices and load/line switching SF6 gas interrupters.

I spent a lot of time working on and learning about racing and cars before college, experimenting on my own cars mostly. Then as part of the Wreck Racing club in college, I led a team of students designing a low-budget race car with custom front and rear suspension, powertrain, and electrical system. I was personally responsible for the designing and building the front and rear suspension, vehicle wire harness, and EFI system (including calibration). I held the position of vice president one year and lead engineer the next.

After school, I went into professional racing, working for a NASCAR Cup team in Spartanburg, SC called HScott Motorsports. As part of the road crew, I traveled to all 36 races each year and to every track test.

Throughout the race weekend, I analyzed data and driver feedback to make vehicle setup changes that improved performance. I ran vehicle-dynamics simulations, instrumented the vehicle for tests, maintained our at-track IT infrastructure, and assisted with pit strategy during the race – first as Second Race Engineer for the 51 car then as Lead Race Engineer for the 46 car.

It was a small team, but our engineering alliance with Hendrick Motorsports and Stewart-Haas Racing gave us access to the best technology in the business. It was a terrific opportunity and an other-worldy experience at times.

I left HSM to get a normal job with benefits and a normal schedule. I got a job with Textron Specialized Vehicles (TSV), working on golf cars and utility vehicles. My team and I developed a new closed-loop EFI system to replace the carbureted fuel system inĀ  the majority of our offerings. This improved fuel economy and startup performance (no more choke), and the system automatically adjusts for altitude. As part of the EFI program, I updated the powertrain governor system to improve low-speed pedal modulation. I also helped design and implement a sound-reduction package for gas-powered vehicles after performing extensive sound testing at multiple facilities.

I’ve gotten more into electronics and computers over the past several years, taking computer science classes on the side and building various related personal projects. I enjoy working on control systems, automation, and data analysis.

Currently I lead an electrical engineering group at TSV. I enjoy learning from the team and finding chances to apply what I’ve learned in my online CS coursework. One of the first projects in this role was leading the development of our vehicle software validation, documentation, and release/revision standards.

I’ve taken advantage of several opportunities to create software tools (mostly in Python) to integrate, process, organize, and visualize data:

  • Altitude-test Data Processor 1 and 2 – time-aligns data from EFI altitude testing with two separate data acquisition systems.
  • EX1 CVT data preprocessor – uses rolling regression to isolate steady-state conditions in engine/CVT test data.
  • Where-used cascade – ingests exports from our PLM and ERP databases and generates graphs and reports that help us understand associations across product lines so we can make better decisions.
  • Smart Gauge model – an OOP model of our innovative touchscreen HMI within the context of our vehicle device network that helped us develop the device logic and data model.
  • Controller-export preprocessor – convert binary controller exports from field vehicles into CSV format (includes GUI automation using Python), combines parameter and fault exports, extracts specific data from each export, then aggregates all exports for trend analysis.

(Any projects I’ve hosted on GitHub have proprietary info scrubbed, often by abstracting file paths into a separate “.gitignore’d” file. The remaining logic of tools like export processors and data graphing is of no competitive interest. In contrast, the logic of the Smart Gauge simulation is the core functionality of our product so can’t be made public.)
