Build me a fast Fortnite private server backend in Go that can handle profile actions and keep player data in sync with the game. I want it to support the core profile changes like adding and removing items, quests, daily quests, and tracking changes with snapshots and diffs so it behaves close to how Fortnite does.

Please make it easy to plug in different storage backends, since I may want to swap databases later. It should also be set up to support the kinds of endpoints Fortnite needs, including MCP style operations and player telemetry, and leave room for party features and shop logic later on.

If you need to check current docs or patterns while building it, go ahead and look them up online. I’d also like a simple default config and a clean way to run it locally as one backend service.
