We have a game being built in Unity. The game is supposed to have real-time multiplayer functions (similar to fps games).
We've experimented with Firebase, but the latency in its realtime database removes it from consideration. Now we're looking for alternatives, or for a skilled freelancer to setup a realtime database for us (this can even be on our private server, which the freelancer has access to).
Please explain in your bid how you are planning to implement the database. Selecting the freelancer will be on the basis of the information they provide in their bid with relevance to the project aim and requirements.
