My professional career started in a big software company as an automotive embedded engineer. I was working as a maintainer of drivers for ethernet chips. I have done lots of hobby projects on Arduino, raspberryPi nodeMCU, esp8266, mbed and STM. I am doing both software and hardware for all my projects. I have 5+ years of experience working as a Lead Software Engineer in the SmartHome sector. I was developing drivers for Zigbee, Mqtt, HomeAssistant, etc. Working in C, C++, Python, Golang and Bash. I was also maintaining and improving build system automation. Making it both easier to use, more versatile and time-saving. I was working with Buildroot and Yocto.
