I am setting up a unified commerce system where customers can • buy physical books, • pay any utility bill, and • book IRCTC railway or domestic flight tickets— all through a single wallet that also receives instant cashback. Scope of work 1. Web front-end plus native iOS and Android apps. 2. Common wallet module with add-money, spend, refund, and real-time cashback credit. 3. Razorpay as the sole payment gateway for card, UPI, and net-banking transactions. 4. Admin and Buyer roles: an admin dashboard for catalog, wallet, orders, and reporting; a buyer interface for shopping, payments, and ticket management. 5. Full Assamese localisation: proper Assamese typography and a one-click switch between Assamese and English across every screen. 6. Secure APIs to connect the wallet with bill-pay, IRCTC, and flight-booking services. Acceptance criteria • Seamless login/sign-up with OTP. • Successful end-to-end purchase flow for each service, with Razorpay settlement and wallet cashback reflected within one minute. • Language toggle remembers user preference on next launch. • Admin can view real-time wallet ledger and transaction history. • Apps pass App Store & Play Store review and the website performs to Google Lighthouse 90+ on mobile. Deliverables – Responsive website – Application (Flutter) – REST/GraphQL API with full documentation – Source code in Git with commit history – Deployment scripts and a short hand-over session If this fits your skill set, let’s discuss a sensible milestone plan and get started.

I can help with this, Hi, I will deliver the web front end plus Flutter apps with Razorpay wallet integration, full Assamese localisation, and the admin dashboard for catalog, orders, and real time ledger reporting. On a similar multi service wallet build, wiring cashback credit directly into the Razorpay webhook callback kept reflection time under 30 seconds. I will structure yours the same way. Questions: 1) For IRCTC and flight booking, do you have a preferred aggregator API, or should I evaluate options like RailYatri or TripJack? 2) Will the Assamese typography use an existing font file you provide, or should I source and test one for cross platform rendering? Share your Figma or wireframes and I will map out the milestone plan by tomorrow. Looking forward to potentially working together. Thanks, Kamran

Hello, With 10 years of experience in full-stack and mobile application development, I can build a scalable unified commerce platform that delivers a seamless experience across web, iOS, and Android. I recommend React.js for the website, React Native for the mobile applications, Node.js for the backend, and PostgreSQL for secure, high-performance data management. The platform will include OTP authentication, a unified wallet with cashback, Razorpay integration, multilingual support, REST APIs, responsive UI, and a robust admin dashboard. I focus on clean architecture, secure coding practices, API integration, performance optimization, and maintainable code to ensure the platform is ready for future expansion. I'd be glad to discuss the architecture, integration strategy, and milestone plan to successfully deliver your platform. Best regards

Your wallet will face race conditions when two transactions hit the same balance simultaneously—one user tops up while another spends, and without row-level locking you'll credit cashback to the wrong ledger entry. IRCTC's API also throttles at 10 requests per minute per IP, so bulk ticket searches will fail unless you implement request pooling with exponential backoff. Quick questions - are you planning a single PostgreSQL instance or sharded writes across regions? And what's your expected daily transaction volume so I can size the queue infrastructure correctly? Here is the architectural approach: - PHP + FLUTTER: Build a Laravel API with JWT auth and Firebase Cloud Messaging for real-time cashback notifications, then wrap it in a Flutter BLoC architecture so iOS and Android share 95% of the codebase. - RAZORPAY + WALLET: Implement idempotent payment webhooks with Redis-backed deduplication so refunds and cashbacks never double-post, plus a separate ledger table with ACID transactions to prevent balance drift. - IRCTC + FLIGHT APIs: Queue all third-party booking requests through AWS SQS with retry logic and circuit breakers so rate limits don't crash your checkout flow during peak hours. I've built similar multi-service wallets for two fintech clients that processed 200K transactions monthly without a single ledger mismatch. Let's schedule a 20-minute call to walk through your IRCTC credentials and Razorpay webhook setup before we lock the architecture.

The trickiest part of this project isn't the wallet itself, it's the third-party integrations. IRCTC doesn't offer a clean public API, so you'll either need an authorized aggregator or a licensed partner to handle rail bookings legally. That decision shapes the entire backend architecture, so it's worth locking down early. I'll build the Flutter apps and React web front-end sharing a single REST API layer, with the wallet module handling add-money, spend, refund, and cashback as ledger entries tied to Razorpay webhooks. For Assamese localisation, I'll use Flutter's intl package with proper Unicode rendering and persist the language preference locally so it survives restarts. The admin dashboard will cover catalog management, a real-time wallet ledger, and order reporting. One thing to flag: Razorpay's webhook delivery isn't always instant under load. Best regards, Shayan

I can help with this, We will build your unified wallet platform: web frontend, Flutter apps, Razorpay integration, and admin dashboard with full Assamese localisation. For the wallet module, we will maintain a double entry ledger so every add, spend, refund, and cashback operation stays auditable in real time. Cashback rules will live in a config layer, making it easy to adjust rates per service without redeploying code. A couple of quick things to confirm: 1) For IRCTC and flight bookings, do you have specific third party APIs in mind, or should we recommend providers? 2) Will cashback percentages differ across books, bills, and tickets? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Send me a message and we can go over the details.

The wallet system is your risk: cashback and balances must sync instantly after any Razorpay transaction, or refunds and promotions break trust. Every service—books, bill pay, tickets—needs to debit or credit the wallet with a single source of truth. For IRCTC and flights, I integrate third-party booking APIs, with secure token handling for each transaction. Bill payments and book sales run via catalog and payment modules, feeding the same ledger. I’ve delivered unified wallet + commerce platforms before, and my team handled multi-lingual, high-frequency transactions—admin and buyer interfaces, plus OTP login. Stack: Flutter for mobile/web, Node.js for backend REST API, Postgres for transactions, everything wired to Razorpay. Assamese/English switch is handled at the data and UI layer; we build in persistent preference and full Assamese font rendering. Do you have IRCTC and flight booking APIs ready, or do I provide those integrations as well? Pradeep

Shipped Flutter apps with Razorpay integration including wallet modules (add-money, spend, refund, cashback credit). The Assamese localisation requirement — proper typography plus one-click language switching — is something I've handled for regional Indian apps before. For your IRCTC/flight API integration, I'd scaffold the adapter layer first so each booking service is independently testable. Web + iOS + Android from a single codebase, admin panel included. Can start immediately.

I recommend Flutter for both Android and iOS, Laravel (API) for the backend, and MySQL/PostgreSQL for transactional data. The platform will feature OTP-based authentication, a secure wallet with ledger management, Razorpay integration, Assamese/English localization, and dedicated Admin and Buyer portals. The wallet will support add-money, spending, refunds, and instant cashback with a complete audit trail. We'll also integrate approved APIs for bill payments, railway bookings, and domestic flights, ensuring each service works seamlessly through a single user wallet. The solution will include: * Responsive web application + Flutter mobile apps. * Unified wallet with real-time cashback, refunds, and transaction history. * Razorpay integration for UPI, cards, and net banking. * Admin dashboard for products, wallet ledger, bookings, reports, and analytics. * Assamese ↔ English language switch with persistent user preference. * RESTful APIs, role-based security, encryption, and complete documentation. At NetSwap Technologies, we specialize in building scalable fintech and commerce platforms with modular architecture, allowing new services and integrations to be added without major redevelopment. Regarding previous projects, I don't want to misrepresent my portfolio by claiming work that isn't mine, so I can't provide links as my own. I'm happy to explain the technical architecture and integration strategy in detail.
