Overview
The Alyn project was a collaboration with the Alyn rehabilitation hospital, focused on creating an embedded system to support advanced assistive technologies.
My role included both firmware development and integration with hardware for real-world patient use.
Responsibilities
- Designed and implemented low-level embedded C++ code for microcontrollers.
- Worked with RTOS environments such as Zephyr and FreeRTOS to ensure deterministic performance.
- Integrated sensors and actuators through I²C, SPI, and GPIO.
- Developed safety mechanisms, telemetry, and diagnostics for medical-grade reliability.
- Supported clinical teams by adapting software iterations quickly for patient trials.
Achievements
- Delivered a stable prototype that significantly reduced engineering time for future iterations.
- Provided end-to-end ownership, from driver-level coding to application logic.
- Helped accelerate development by several months compared to initial project timelines.
Tech Stack
- Languages: C, C++
- RTOS: Zephyr, FreeRTOS
- Hardware: ARM Cortex-M, custom PCB with ADC/DAC sensors
- Tools: GDB, UART debugging, Git
