I've been working (for the last 8 years) in design and implementation of data acquisition, transmission and processing. For the low-level stages, I can use several platforms like Arduino, ESP, STM32, etc., using several communication protocols. Remote data report via MQTT. Data storing and processing, mainly using Python and C#.
My previous experience was designing Telecommunication networks in a TELCO.
Other skills include design and advice on of off-grid Solar Energy systems.
