Embedded Systems Engineer | Control Engineering MSc

Hello! I am an electrical engineer with over 7 years of experience in embedded systems and a strong background in control engineering. My main fields of expertise are power electronics, IoT and signal processing, but I'm comfortable adapting to the specific needs of each project. If you need guidance on the best way to frame your electronics project, someone to do your embedded software (firmware) coding, or if you need help tuning a controller, I'd be happy to work with you. My experience: • Embedded software and hardware architecture • Control system design and implementation • Firmware development in C/C++, bare or RTOS • Python scripting • IoT protocols: LTE, MQTT, TCP/IP, HTTP, CoAP, BLE, GNSS • Communication protocols CAN, SPI, UART, I2C • Various boards and MCUs: STM32, TI, AVR, nRF, ESP, Arduino, RPi
