I need a full-stack build of a sports betting site that automatically adapts to both desktop and mobile screens. The core of the project is real-time functionality—odds must refresh instantly and every click during live play should feel snappy. Key feature set • Live scores and updates fed by an authorised API • In-play betting with dynamic odds adjustments • Secure user account management covering sign-up, KYC steps, wallet, and transaction history You are free to choose the tech stack as long as it scales well (Node, Laravel, or a comparable framework on the back end; React, Vue, or similar on the front end; PostgreSQL/MySQL for data). Clean, commented code and a concise deployment guide are required so I can maintain the platform after launch.
