Aston Dynamics
Connected with Aston Dynamics through their sponsorship of the University of Toronto Formula SAE team. What started as a flexible internship evolved into leading firmware development for their full lineup of intelligent trailer brake control products.

Leading Aston's 3-person Canadian firmware team: breaking product requirements into scoped work, owning architecture, reviewing PRs, and interviewing candidates. I define the firmware's peripheral requirements and review IC selections with the electrical team, and collaborate with Aston's Australian subsidiary on larger systems projects. Firmware is written in sync/async Rust with generated ESP-IDF C bindings.
Took full ownership of firmware development across all wireless products, and now coordinate all wireless certifications. I select the certification route for each product and act as the company's point of contact for the full process, coordinating testing with the TCB that runs the tests and advises on certifying in each region. The hand-held remote - a free in-box accessory that controls the Delta over BLE - has already been through and passed the process.
Also developing an automated testing system for production assembly - writing firmware for a custom test PCB that validates Delta inputs/outputs, communicating over serial USB with a desktop app for technicians to coordinate tests.
Testing & Development Intern
Worked in a cross-functional team of 3 interns to transition the brake controller project from Australia to Canada, with one person on electrical, one on controls, and myself on firmware. Led firmware development using embedded Rust and ESP-IDF on ESP32-C6. Designed a custom BLE streaming protocol for OTA firmware updates, researching OSI/TCP-IP layers to optimize packet size and error handling over BLE's limited bandwidth - reducing transfer time from 3 minutes to 30 seconds.
Identified communication gaps with our external app development team and took initiative to establish structured coordination through regular meetings and a GitHub issues system. Conducted all the RF and EMC certification research across US, Canadian, and Australian/NZ regulatory bodies, discovering our original hardware would be prohibitively expensive to certify and guiding the selection of pre-certified components.
The Delta
Embedded Rust firmware for a trailer brake actuator on ESP32-C6. Features an intelligent braking control loop, custom BLE protocol with OTA updates, and FCC certification
Hydrapro Mobile App
Native Rust BLE library for the Delta Series mobile app. Built with btleplug and exposed to React Native via codegen FFI (uniffi-bindgen), handling all actuator communication and business logic
