Enhance and Complete React/.NET RPG System

I have a semi-complete web- and app-based multiplayer RPG System that I want another freelancer to work on until completion. It is written in a React front-end with a .NET C# back-end. It targets the web primarily and will use Capacitor to become workable on Android and iPhone...
