If you're looking to have a self-hosted platform for anything using cryptocurrency here are a few things you'll need.
1) knowledge with JSON rpc calls.
2) Your own node
You could run functions such as wallet notify and txnotify - this can be set up in the bitcoin.conf file so whenever you get a transaction in or out/ and a confirmation that file is run, to store the information you need to your database.
It's pretty simple, but you must be aware of hackers since they will target your node if it's not secured. I.e PORTS and always encrypt your node with a strong password (if you lose your password, your coins are gone.)
