We are looking for a senior API integration expertto design and implement a scalable, production-ready integration layer connecting multiple external systems across: PMS (Property Management Systems)– accommodations POS (Point of Sale Systems)** – restaurants BMS / Booking Management Systems** – tours, activities, transfers This is not a basic connector project. The system must be architected correctly from day one to support scale, real-time synchronization, and multi-tenant logic. ## Required Integrations 1.
