I’m launching a custom football credit platform whose revenues will be channelled to charitable projects, and I need someone to turn the concept into solid, production-ready code. The core of the build is a real-time odds engine that pushes live prices straight into the user interface without lag. Automated odds updates are non-negotiable, so your solution should comfortably poll or stream data from the feed of your choice and refresh markets instantly; if you can leave hooks for future odds comparison or historical analysis, even better. Running alongside the odds module is a full agent management system. Agents drive volume on the site, so the back-office has to give them a clear view of their business while keeping my overhead light. The module must handle: • Agent registra...
