Hotel Reservation System with Online Booking

I need a full-scale hotel management platform, but the very first milestone has to be a rock-solid Reservation System that guests can use end-to-end online. Visitors must be able to check real-time room availability, create a booking, receive instant confirmation, and manage their stay dates from any device. On the back end I want a clean dashboard where staff can see incoming reservations, apply rate rules, block rooms, and override allocations without delays.

Online Booking is the only feature that must ship in this phase; modules such as Billing & Payment or broader Inventory Management can wait until the reservation flow is proven in production, yet the architecture should leave room for those add-ons. A responsive web interface, secure database design, role-based access, and succinct technical documentation are expected deliverables. Please outline the tech stack you prefer, your timeline for an MVP, and any similar systems you have launched so I can gauge fit quickly.
