I want to launch a fully-featured, cloud-hosted lottery platform built on a hardened Node.js backend with a reliable database layer. New players will sign up with a classic email-and-password flow, then complete KYC before they can fund their wallet or join a draw. The exact KYC data points can be finalised together, but the process must be seamless and compliant. Core flow • A user tops up an internal wallet via PayPal (gaming category enabled), buys entries, and watches their balance update in real time. • On draw day a server-side, provably-fair randomiser selects winners; every draw, ticket purchase, and payout is written to an immutable audit log. • From my side I need an admin dashboard that shows live player stats, transaction history, and lets me trigger or schedule draws, refund tickets, or freeze accounts instantly. Security and reliability – Follow OWASP practices, encrypt sensitive data at rest and in transit, and add role-based access throughout the dashboard. – All key actions (login, deposits, draws, payouts, KYC decisions) must hit an audit table that cannot be altered outside privileged migration scripts. – The finished stack should run behind HTTPS on a cloud instance (AWS, GCP, or DigitalOcean—happy to discuss), with deployment scripted so I can spin up staging and production easily. Deliverables 1. Source code (Node.js + database schema) in a Git repo 2. Responsive user site, ticket purchase module, and wallet UX 3. Admin dashboard with real-time metrics and draw controls 4. Secure random draw service with verifiable output 5. KYC workflow wired to the registration process 6. PayPal payment gateway integration, ready for live gaming approval 7. Installation scripts / CI-CD pipeline and cloud deployment guide 8. Post-launch hand-over session and basic documentation I value clean, well-commented code, transparent communication, and a clear pathway from MVP to production. If you have experience with gaming-sector payments and provably-fair algorithms, let’s get this built.

Proposal: I am excited to help you build a secure, scalable, and fully cloud-hosted lottery platform with a hardened backend, real-time wallet system, KYC integration, and PayPal gaming support. The system will be designed with security, transparency, and long-term scalability in mind. Problem / Current Situation: Launching a lottery platform involves high security risks, payment compliance challenges, and trust concerns around fairness. Without strong encryption, audit logging, and provably-fair draw logic, the system can face fraud, manipulation risks, or regulatory issues. Managing real-time wallets, KYC verification, and admin controls also requires a well-structured backend architecture. Solution: I will develop a secure backend with encrypted data storage, OWASP-compliant practices, immutable audit logs, and role-based admin access. The platform will include user registration with KYC workflow, PayPal wallet integration, real-time balance updates, and a provably-fair random draw engine with verifiable outputs. A responsive admin dashboard will allow full control over users, transactions, draws, refunds, and reporting. Deployment will be configured on AWS/GCP/DigitalOcean with CI/CD and proper documentation. We have a team of experienced developers specializing in secure backend systems, payment gateway integrations, and scalable cloud infrastructure, ensuring a production-ready and reliable platform.
