Setting up own map server for routing.

I want to build my own map server which users can use for routing, directions etc. Currently, I have only st up an OSRM server which can send back json response using this tutorial here and it works perfect for me. Now I want to take it to the next level and implement tiles like, users get to see their route and maps. I also want to add an auto-complete address functionality. I have read a lot of articles like these here and its further links down. But I am not getting it together. Will following these steps help me achieve my goal. What tutorial should i look for auto-complete, is Nominatim or Pelias is required and how they can be integrated with OSM. Basically I want to build something similar to openrouteservice o my own server.
