About Me
I am a passionate Embedded Systems Engineer currently pursuing Industrial Computing and Automation Engineering at the National Institute of Applied Science and Technology (INSAT) in Tunis, Tunisia.
With extensive experience in firmware development, real-time systems, and IoT solutions, I specialize in creating robust embedded systems using technologies like STM32, ESP32, FreeRTOS, and various communication protocols including UART, SPI, I2C, and wireless technologies.
Currently working as a Firmware Engineer at Mare Custos, I focus on developing resilient OTA firmware update systems, implementing micro-ROS transports, and building comprehensive testing frameworks for embedded applications.
