Experienced Full-Stack Developer for Web-Based Casino Game with Mobile Banking Integration

I am looking for a skilled developer to build a web-based betting/casino game accessible via a link. Key Requirements: - Core Logic: A betting game (similar to crash or slots) where winning/losing directly affects the user's balance. - Payment Integration: Seamless deposit and withdrawal system using Bangladeshi mobile banking (bKash/Nagad). - User Management: Secure login and a persistent database to store player account IDs and balances. - Security: Robust anti-fraud measures and transaction verification to prevent fake transaction IDs. - Platform: Responsive web design so it runs smoothly on mobile browsers via a direct link. Please share your previous work, especially any projects involving payment gateway integration or casino games.
