B2B/B2C Travel Booking App

I am looking to have a single mobile application built that serves both ends of my travel business. On the B2B side, partner agents need a clean interface where they can log in and handle booking management—creating, viewing, modifying, or cancelling reservations for their customers in real time. On the consumer side, travellers should be able to search available flights, hotels, and packages and complete a seamless booking flow from discovery to payment.

A consistent look-and-feel across both user groups matters to me, but the journeys will differ slightly, so thoughtful role-based navigation is essential. I am open to your recommended stack—whether Flutter, React Native, native iOS/Android, or another approach—as long as the final build is stable, quick to load, and easy to maintain. If you have experience tying apps into travel APIs or inventory feeds, highlight that; I already have supplier connections ready to plug in once the screens are wired.

Core deliverables I expect:
• Fully functional iOS and Android apps with separate B2B and B2C log-ins
• Booking management module for agents
• Consumer search-to-checkout flow
• Basic admin console or back-end so my team can view data and run reports
• Source code, installation instructions, and post-launch support window

Please outline your proposed tech stack, milestones, and any similar work you have shipped. I am ready to move quickly once I see a clear plan.
