Senior firmware engineer focused on Bluetooth Low Energy and Zephyr RTOS, delivering end-to-end embedded products from design to production.
BrazilWhat I'm looking for
I’m a Senior Firmware Engineer with 30+ years of hands-on experience building embedded systems across Nordic nRF54L/nRF52-nRF53-nRF54L, Silicon Labs EFR32BG12, and ESP32. I pair deep expertise in Bluetooth Low Energy and RTOS firmware with full product-lifecycle ownership, from hardware design through production deployment.
In recent roles, I’ve led fully remote hardware and firmware delivery using C/C++ and Zephyr, including real-time sensor data processing for motion analysis with concurrent device connections. I’ve also developed IoT firmware for smart agriculture and large-scale device ecosystems—implementing protocols like MQTT, CoAP, and LwM2M—while improving power efficiency and BLE connection stability through systematic testing and protocol stack tuning.
