  I work in the development of firmware for embedded devices, with a focus on IoT and M2M, in sectors such as sanitation, oil/gas, agribusiness, energy, and water. I utilize technologies such as 3G e 4G with network protocols like TCP(S), HTTP(S), and MQTT(S). Additionally, I develop for embedded Linux, taking care of the respective application architecture and focusing on good programming practices and object-oriented design, using C++17 and low-level libraries for Linux systems, as well as applying the best design patterns for embedded systems. Furthermore, I also contribute to the software team, where I work on developing applications that communicate with the devices using various protocols. Show less
