Sergey was an excellent candidate, he immediately understood the brief and his knowledge of modbus and the bi-directional communications of modbus was excellent. He managed all the data and setup the system to store the data in multiple remote databases in real time.The quality of the work done was excellent. He really turned around this project fast. I would recommend him highly
