I need an end-to-end travel-booking solution that mirrors the seamless experience of MakeMyTrip, EaseMyTrip or Ixigo, delivered as: • A responsive website • Native iOS and Android apps Core features to build — Flight and hotel search, real-time availability, and booking flows — Dynamic price comparison for both flights and hotels, pulling live fares from multiple GDS/APIs — Secure user accounts created and verified through phone-number OTP (no social or email sign-up at this stage) — Modern, scalable backend in Node.js with well-documented REST/GraphQL APIs — Clean, fast frontend (React, Next.js, or a comparable framework) with intuitive UX and optimized mobile performance — Single admin console for inventory, bookings, prices, promotions, refunds, and basic analytics High-level process 1. Architecture & tech-stack proposal 2. UI/UX mock-ups for web and apps 3. Modular development with weekly demonstrations (web first, then mobile) 4. End-to-end testing, including payment gateway simulation, OTP flow, and live fare sync 5. Deployment to App Store, Google Play, and a cloud host of my choice, followed by 30-day post-launch support Deliverables • Source code repositories • Production-ready builds for iOS, Android, and web • API documentation and basic user guide • Deployment scripts / infrastructure as code (Docker, Kubernetes, or similar) If you have prior experience integrating flight and hotel APIs, handling real-time pricing, and delivering polished cross-platform products, I look forward to seeing your approach and timeline.
