Hello, my name is Greg.
I am a senior software engineer currently working in the automotive industry for General Motors. My career has focused on control software development for battery electric vehicles - with a strong focus in hardware and software integration, test, and validation.
I have a passion for learning, creating, and houseplants. To see a snapshot of my capabilities - from personal or academic projects - check out the Selected Work section below.

Selected Work
NASA Exoplanet Watch - Citizen Science
Contributor to NASA’s Exoplanet Watch program, turning raw telescope images into transit light curves that refine exoplanet orbital timing. I built a locally hosted web application around the EXOTIC reduction pipeline that ingests raw MicroObservatory and checked-out .FITS data, automates star chart coordinate matching with user confirmation, and produces publication-ready light curve charts. All results are published to the AAVSO Exoplanet Database under observer code EGRA.
Stack: Python, Pandas, EXOTIC Reduction Analysis
Result: 6 observations published to AAVSO

Regenerative Braking Control Method
Analysis of six-switch inverter control strategies for recovering braking energy with a brushless DC motor. I built an electromechanical model in MATLAB/Simulink and used it to compare inverter switching approaches for regenerative braking.
Stack: MATLAB, Simulink, SimScape

Satellite Attitude Control System
Design and analysis of a PID-based attitude controller for orienting a satellite relative to a reference. The study compares open- and closed-loop response and evaluates the controller’s stability and noise rejection.
Stack: MATLAB, Simulink, PID control design

3D Modeling & Printing
I enjoy being able to take ideas from conception to reality, which makes 3D printing a very rewarding hobby. All of the prints shown here are modeled by myself using AutoDesk Fusion360. Check out the Printables links for more information.
