Websocket Implementation

I am looking for a freelancer who can solve errors in our WebSocket functionality using JavaScript and the Socket.IO framework. The project requires the WebSocket to be implemented on both the client side and server side. We want it for multiple users. We already have it for one user. I am attaching the relevant screenshot too for your reference.

Ideal skills and experience:
- Strong knowledge of JavaScript programming language
- Experience with Socket.IO framework
- Familiarity with both client-side and server-side websocket implementation
