Hello!

I am ready to complete the task of transitioning from polling requests to a permanent WebSocket connection. Here’s what I will do:
I will replace the current polling mechanism with WebSocket (or Socket.IO, if a fallback and auto-reconnect are needed). I will implement a stable two-way connection with heartbeat/ping-pong, handling disconnections and auto-reconnection.
I will optimize the server logic so that data is pushed to the client immediately upon arrival, without delays.
If necessary, I will integrate authorization and session transfer through WS.
I will update the client application for the new real-time channel.
If needed, I can also set up WS clustering through Redis.
