Full-Stack Platform Build & Hosting

Job ID: 40177274

Budget: ₹1,500 – ₹12,500 INR

I’m building a production-ready web platform that brings together user registration, a live bidding marketplace, real-time messaging, a conversational chatbot and seamless checkout with credit or debit cards. The public-facing side must be a fast, responsive React application. Behind the scenes, I need a robust back-end of your choice.
Key objectives
• Secure user auth (JWT or OAuth) with role management and full HTTPS encryption
• Bidding engine that supports creating, updating and closing auctions in real time
• In-app messaging/notification system
• Credit/Debit card payments or other payment gateway as we suggest
• NLP-driven chatbot for common user queries and support
• Admin dashboard for analytics, user control and fraud monitoring
• Continuous deployment to Google Cloud (Cloud Run, App Engine or GKE) with automated testing

Deliverables
1. Source code for frontend (React + modern tooling) and backend
2. Google Cloud infrastructure as code and deployment scripts
3. Detailed API documentation and a quick-start guide
4. Post-deployment support to fix any launch-blocking bugs

Acceptance criteria: all core flows—sign-up, regisration, bidding, chat, payment and admin—must work end-to-end on the live Google Cloud URL and pass agreed test cases.

If this scope excites you, tell me which back-end stack you’d suggest, how you’ll secure payments and data, and a realistic timeline for delivery. If you are new one On platform that doesent matter just show me one website you have build in latest.
