When I started to work at TRAXxs (we are doing some pretty cool stuff there btw 🙂 ), there was a lot of things to put in place to setup our back-end / front-end layers. The cool thing was the possibility to select the technologies we will use… Let’s go Docker, Node.js, Mongo + other cool stuff then (a little bit of Clojure + some Go, as they are languages that Im also very interested in).
At TRAXxs, we are working on connected insole devices. To keep it simple, on the server side (the part I’m in charge) we collect the data, make some analysis and expose it to the clients via api and web front-end. There is, obviously, much more than this but this is a cool summary.
