Summary
🤩
Rockstar🎓
Top SchoolRobert Lubos is a Senior Firmware Engineer with nine years of embedded systems experience, currently driving networking and IoT features at Nordic Semiconductor. He specializes in low-level C/C++ firmware for cellular and Thread stacks (nRF91, nRF9160) and has contributed to high-profile open-source projects like Zephyr and OpenThread, focusing on TCP/IP, DTLS/TLS, and BSD socket interfaces. His background in automatics and robotics (M.Sc./B.Eng., AGH) and early PLC work give him a strong systems-thinking edge when bridging hardware, modem firmware, and cloud-facing protocols like MQTT/CoAP. Notably, he has improved multicast DFU tooling and core router/crypto logic in OpenThread, showing both practical product impact and deep protocol expertise. Colleagues rely on him for robust networked embedded solutions that integrate radio, OS, and application layers.
