I need a production-ready backend that lets an AI engine both analyse and act on live cryptocurrency markets. The service must connect to Coinbase and Binance simultaneously, pull real-time order-book and trade data, and feed that into a prediction module that forecasts near-term price movements. From those forecasts the system should automatically execute day-trades, swing positions, and rapid scalps while keeping an up-to-date record of every open order, closed position, and cash/coin balance so I can view my portfolio value at any moment. You are free to choose the stack, but the finished solution has to expose a clean REST or gRPC interface so I can plug in my own front-end later. Secure API key storage, robust error handling, and rate-limit compliance for both exchanges are essential. Deliverables • Source code for data ingestion, model inference, order execution, and portfolio tracking • Docker-compose or similar script for one-command deployment • Brief README explaining environment variables, endpoints, and how to retrain or swap the prediction model • A short demo (recorded or live) showing the AI place at least one automated trade on each exchange while logging the result
