Experienced QA, functional tester, system tester I have personal interest on integration sensor devices with Arduino/stm32f/Raspberry and create IOT. In order to do that I face several SW programming language since Java, C, arduino C, python. Another great interest is integrate Opencv functionalities along with my traffic monitoring system running on Linux server, in this way my webcam count the number of vehicle which crossed my road all using image recognition/background subration and vectors. During one of this projects I also have integrated GPS along SIM808 (GPS/GPRS) with my backend database/webserver, the device itself update its own position via GPRS and push to database, after that I could monitore the device moviment my own webpage map (google map/baidu map)..
