A few of the projects I'm most proud of are listed here. There are more (mostly smaller) projects on GitHub, but a lot of the larger projects I've worked on are still under NDA.
Terrain Relative Nav
I helped Astrobotic implement a Terrain Relative Navigation algorithm to improve Lunar landing accuracy from kilometers to meters. I wrote much of the flight application, middleware, and hardware-in-the-loop test methods for the flight sensor.
Enhanced Radio
From 2014 to 2021 I was HW and SW lead on a variety of amateur and ISM radio projects. I designed the HamShield and Edison Explorer block, and wrote demo firmware for them. The company is defunct, but our designs are still open source.
GMD
I offered embedded electronics and firmware consulting through my company Good Measure Design. This work ranged from quantified self devices to satellite tracking algorithms.
Activity Recognition
My Master's Thesis (pdf) on identifying and tracking trans-tibial prosthesis use via inertial sensing. I used classical (non-deep) machine-learning to classify activities, which allows prosthetists to better understand fit and function of the prosthesis.
