Hello, thanks for posting this project. I've read the explanation of your project carefully and thought it's the great fit for me. Because: I have extensive experience developing secure, scalable web platforms with automatic payment integration and random number generation, tailored for online raffles and similar applications. For your project, I recommend using Node.js with a modern backend framework such as NestJS, paired with a robust frontend in React or Vue for responsive user panels. Payments can be integrated via providers supporting card and PSE transactions, and the random draw logic will be coded for full auditability. I'm experienced with building admin and user dashboards, real-time notifications, and ensuring GDPR-compliant data security. I’d deliver a clean, secure codebase, an intuitive admin panel, and implement best practices for modularity and future feature expansion. In my detailed project proposal, I’ll outline the complete system architecture, technology stack, milestone-driven timeline (covering MVP delivery, testing, launch), and specify security/unit testing strategies and optional post-launch support. May I ask if you already have a preferred payment gateway, or should I advise on the optimal solution for your region? Looking forward to hearing from you. Warm regards, Vitalii.
