I'm an engineer who likes building things. This is where I write about the stuff I've made over the years.
Infrastructure, embedded systems and backend work
CI/CD to embedded targets · Undergraduate Honors Thesis
For my honors thesis, I built a CI/CD pipeline that compiles microcontroller firmware in the cloud and beams it to microcontrollers buried deep inside a solar race car.
Open source
Our custom boards used a crystal oscillator that mbed-os did not support, so I fixed it upstream. My code now ships in an RTOS used by strangers, which is a fun thought.
Distributed vehicle network · zero downtime
The nervous system of Sunswift 7: a custom CAN network tying 8+ sensor and actuator nodes together. It carried 1,900+ messages with zero downtime across the 3,200 km World Solar Challenge which we won.
Spring Boot REST API · team of 5, 2023
A full restaurant wait-management system from my university capstone. Customers order, the kitchen cooks, wait staff get pinged. I built the backend: a Spring Boot REST API in Java sitting on an SQLite schema.
Mechatronics and control systems
Control systems · personal project
A motorized two-axis mount for a 114 mm Newtonian reflector. Essentially a 2DOF robot arm, made for aiming at the stars.
The person behind the projects
Hello! I'm Leonard, a software engineer with a keen interest in software that intersects with the real world. Over the years I've worked on vehicles, embedded systems and web projects, both solo and as part of larger teams.
This site is a living collection of that work. Have a browse through the projects above. Each one links to a longer writeup where I get into the weeds.
