Summary
🤩
Rockstar🎓
Top SchoolJonathan Rico is an Embedded Software Engineer with five years of hands-on experience designing low-power microcontroller systems, PCB layouts, and BLE-enabled IoT devices. He has contributed to high-profile open-source projects such as the nRF Connect SDK and the Zephyr RTOS, focusing on BLE controller and host stack improvements, L2CAP, and SoftDevice Controller integration. Comfortable across circuit design, firmware in C for ARM/MSP430, and network stacks, Jonathan pairs hobbyist electronics prototyping with production-grade embedded development. Based in Canada and now at Garmin, he brings a practical blend of hardware troubleshooting and protocol-level Bluetooth expertise—evident from adding LLPM/sample support for the nRF52840 dongle and periodic advertising fixes.
