GPS can be jammed, spoofed or simply unavailable. At Draper I worked on an alternative navigation system for the Air Force's positioning, navigation and timing capabilities, writing the operator interfaces in Python and C++. That software went out to clients who were not going to read my code to work out what I meant.
I also built a full-stack tool for the microelectronics teams that parses sensor data and does schema matching with LLMs. Matching two schemas is a judgment call, and engineers had been spending days on it. With a language model doing the judging it takes hours.
The summer intern project is the one I would show first. Eight of us built a mini lunar rover prototype sized to fit an Artemis payload, so the mass and volume budgets were fixed before anyone wrote a line of code and the decisions after that were negotiations against them. I led the robotics programming: sensing, autonomous navigation, drivetrain control and the state machine, in ROS2 and Python.
Then we defended it for two hours in front of forty domain experts and company leads. Nobody had taken my design reasoning apart that thoroughly before, and I have never learned as much in an afternoon.
