Backend rewrite ☂️

[siddharthkp]

This is an umbrella ☂️ issue for the work to be done on the backend.

I wrote the original backend over a few days, it's help together with much duck tape and bandaids

Things to remember this time around:

• [ ] Error handling
• [ ] Database abstraction
• [ ] Ensure uptime (catch error + keep it running)
• [ ] Reference a build by it's commit hash, not a long json string
