What I'm looking for

I seek senior embedded/firmware roles working on performance-critical IoT, RF or aerospace projects with strong engineering teams, clear QA/V&V practices, and opportunities to lead optimization and system integration.

I am a senior real-time software, firmware and DSP engineer with 25+ years of embedded C/C++ experience across Linux, RTOS and bare-metal platforms. I specialise in algorithms, firmware optimization and device bring-up for MCU/CPU/DSP/GPU/AI accelerators.

My background spans defence, medical, satellite, telecoms and industrial IoT: I contributed to projects for Watlow, BAE, Alén Space, Viavi, GE Oil & Gas, Toshiba, Qualcomm and others. I have hands-on experience with kernel/device driver design, Yocto builds, multithreading, RTOSs and deep hardware interfacing (SPI, I2C, CAN, PCIe).

I deliver end-to-end results including algorithm design, MATLAB/Simulink and RF simulation, unit/V&V testing (DO-178C, IEC 62304, MISRA), CI/CD and secure update mechanisms. Recent work includes PX4/ROS2 UAV integrations, Yocto for STM32MP, Jetson CUDA AI optimization, and SDR/ADS-B RF projects.

I am a collaborative team player with an easy-going personality, quick to learn new technologies and adopt Agile practices, focused on high-quality, performance-critical embedded solutions.
