Ask HN: Building Real time Data Platform to collect streaming data

I am building Real time Data Platform to collect streaming data from different sensors. I would then calculate some metrics based on the different data (factors) I receive and show in a real-time dashboard the data.

I have expertise in developing the front end; so it's not an issue. I am trying to find what is the best way to build real-time data platform ? what are some good and working architectures that you recommend (eg: Storm .. etc). Which technology stack do you advise (Node, Go, Scala, .. etc ) ?
