I’m expanding an online platform that combines traditional casino play with real-time sports wagering and need an experienced full-stack developer who is comfortable living in the Node.js world. The core application is already running; what I need now is someone who can dive into the existing codebase, clean up what’s there, then roll out new features end-to-end—from the API layer through to whatever front-end framework we decide fits best. You will be working on typical betting-site requirements such as user sessions, wallet logic, odds feeds, bet settlement and the game catalogue, but I’m deliberately leaving the exact feature list open so we can prioritise together once you have reviewed the repo. Clean, well-documented code, solid unit tests and a security-first mindset are non-negotiable since we handle real money. If you’ve previously integrated casino game providers, live sports data feeds or payment processors with a Node backend, that experience will put you at the front of the queue. Send a brief note outlining comparable projects, the stack you used and the part you personally built, and I’ll share the Git repo plus a short technical task so we can confirm we’re a good fit before kicking off the main milestones.
