Project Overview I am building a SaaS platform for forex and crypto traders. Users will be able to: • Sign up and log in • Link their MT4/MT5 trading accounts • Link their crypto exchange accounts (e.g., Binance, Kraken, KuCoin) • Write trading strategies using plain text prompts or a visual workflow builder • Backtest the strategy • Deploy it to live trading • Monitor trades, P&L, and logs in real time The frontend UI will be built with Lovable (AI code generator), so I mainly need a strong backend/full-stack engineer to implement the core trading logic, integrations, and architecture. Here’s what I need you to put in place: • MT4/MT5 integration: authenticated order routing, position tracking, and real-time quote streaming • Crypto execution: unified connectivity to top exchanges with smart order handling and high-frequency performance in mind • Strategy engine: a scalable, multi-tenant service that loads Python strategies, executes them automatically, and logs every decision for auditability Additional context – All strategies will run without manual intervention, so latency, fault tolerance, and a solid back-testing module are critical. – The front end can be the framework of your choice so long as it pairs cleanly with our Python back end and delivers responsive, chart-rich pages. – Clean, well-commented code and a concise deployment guide (Docker-based or similar) are part of the final hand-off. If you have deep experience marrying MT4/MT5 APIs with Python microservices, low-latency crypto execution, and automated trade logic, I’d love to see examples of your previous work and discuss timelines.
