Dear sir,
The bid is just arbitrary. Pls. don't care about it. If you could share more scope, I could revise the bid.
Let me introduce myself. I'm Patrick. I'm familiar in node.js, mongodb, mysql. I use geolib to detect geofence. I have experience in writing few GPS tracking parser to collect lat, lon, taking picture. Might you share your device specification and commands which you will use? Thanks.
