website game developmentt

Full-stack javascript developer

Need to build a web app with an embedded Unity app (already built) and a HTTP API.

The web app will enable users to sign up, connect their crypto wallet (eg Metamask).
Once users have signed up they are able to challenge each other by betting crypto and playing the embedded game against each other.
After each game the crypto allocated for the game gets distributed to the winner's wallet, a fee is taken by the website and sent to its wallet.

Web app
- SPA (react) application
- embedded Unity app

HTTP API
- REST/GraphQL - protocol for the API
- NodeJS - runtime environment (JavaScript)
- a serverside application that handles
- users - creating new users, authentication
- games/rooms - creating games, transferring crypto money after games

Game/money flow
- User signs up
- user connects wallet
- starts game
- sends BTC to Emo's wallet
- game ends
- money sent from Emo's wallet to winning player

You need someone with following skills imo:
JavaScript
NodeJS
React
