Programming a daemon to retrieve data from websocket
Programming a daemon to retrieve data from websocket in RUST
which will:
Take a list of all cryptocurrency exchanges from redis (an example list in json will be provided).
Each exchange has:
urlfor connecting to WebSocket,JSON schema (or mapping) indicating which field in the message to parse.
The daemon must connect to these WebSockets, read the coin rates and other fields from the schema, and store them in Redis.
4. Proxy support
There will be a separate thread for each exchange, and it should be possible to monitor the connection status to the exchange and the speed at which the daemon updates data for each pair separately.
Example config for exchanges, in redis each exchange will be a separate key and value, for example exchanges_binance

I have reviewed your task. I have relevant experience working with WebSockets in Rust. In particular, I wrote an RPC bot in Rust for mempool backrun and monitoring price drops on the DEX Uniswap v2, which required high-performance handling of real-time data streams.
From other experience — developing microservices for platforms like Deezer and SoundCloud, where I created a CDN-like infrastructure for sharing subscriptions among multiple users. In this project, I actively used Redis for state storage and caching, so I am also well acquainted with it.
If you need confirmations of my experience, please message me privately, and I will provide the necessary information.
I will also connect tracing: For logging and monitoring the state of the daemon.

Good day.
I can develop a daemon in Python or C++. I have over 20 years of experience working on commercial projects. Feel free to contact me.
