USDT Trading Platform with Live Data

I need a lightweight trading platform focused on USDT pairs where price moves appear the very moment they happen. The heart of the job is a real-time market-data feed pulled directly from major crypto-exchange APIs and streamed to the interface with sub-second latency.

Here is what I expect:

• A small but solid back-end service that connects to one or more exchanges through WebSocket or REST, normalises the data, and keeps it flowing without interruption.
• A front-end dashboard that displays live tickers, order-book depth and last-trade history for each selected pair. The visual layer can stay minimal for now; clarity and speed are more important than heavy graphics.
• Clean, well-documented code and a short deployment guide so I can reproduce the environment on another server later.

If you prefer to add extras—such as account management or advanced charting—feel free to note that in your bid, but the must-have is the real-time USDT market feed working flawlessly end to end.
