Back to original languageAbout Mohamed
I help teams develop and integrate embedded systems, from firmware to on-target testing and hardware integration.
I primarily work in C/C++ and Python on microcontrollers and embedded platforms: STM32, ESP32, nRF52, Arduino, FPGA SoCs, Zephyr, and FreeRTOS. I can be involved in firmware development, sensor integration, inter-board communication, low-level buses, and IoT prototypes.
I am also accustomed to using Python to create tools around embedded systems: automation scripts, MQTT communication, report generation, and integration with GitLab CI, PyQT graphical interfaces...
Topics I can help you with: connected objects (IoT), microcontroller firmware, BLE, LoRaWAN, SPI/I2C/UART/CAN, ADC acquisition, signal processing, low-power systems, hardware/software integration, and technical documentation.
I worked at Airbus Defence & Space on the validation of embedded equipment, then on projects involving embedded AI, sensors, energy harvesting, and connected systems.
I can assist with feasibility studies, existing prototypes, architecture design, firmware development, integration challenges, or transforming a proof of concept into a cleaner base.
