Summary
🤩
Rockstar🎓
Top SchoolLucas D is a Senior Embedded Engineer based in London with nine years of experience building connected devices, RTOS-based gateways, and test infrastructure. He has led architecture and firmware design for commercial products—from a GSM BLE gateway and concrete BLE sensors to a child sleep companion—often driving end-to-end solutions that include cloud APIs and factory test systems. An upstream contributor to the Zephyr RTOS, he implemented Quectel cellular modem drivers and integrated cellular telemetry into Zephyr samples, showing both product and open-source chops. Comfortable across C/C++ firmware, FreeRTOS/Zephyr, Python test frameworks and Go backends, he blends hands-on driver work with system-level design and quality engineering. Notably, he designed custom testbenches deployed on NixOS-powered Raspberry Pi units, reflecting a pragmatic approach to reproducible, production-focused testing.

Contributions summary:Lucas primarily focused on adding support for cellular modems within the Zephyr RTOS. They implemented drivers for specific Quectel modems (EG25-G) and added functionality for retrieving cellular information, including signal strength and modem details. The user also integrated the new modem support into existing cellular modem samples within the Zephyr project. Furthermore, the user made several code adjustments to accommodate new hardware models and fixes size-related issues.
