I’m ready to turn my sports-prediction concept into a fully working product that lives on the web and inside native apps. The core build includes: • A responsive web platform written in modern HTML, CSS and JavaScript • Companion iOS and Android apps built from the same API layer • Secure, scalable backend with both email-and-password and social-media login options • Real-time live-score feed, a flexible betting engine, and a points-based user leaderboard You’ll design and code the full stack—database, REST/GraphQL API, admin dashboard, front-end UI, and the two mobile shells—then help me deploy to production stores and hosting. Code quality, test coverage, and clear documentation are critical. If you’ve shipped similar sportsbooks or fantasy platforms before, let’s talk about architecture choices and timelines so we can get this in fans’ hands.
