Build and scale the guest-facing reservation Booking Engine on a revenue-critical path used by tens of thousands of properties. Implement new architectures and features as the team migrates toward service-oriented, microservices, and event-driven systems. Design PHP APIs and integrations, model availability/pricing/reservations data, and ensure correctness, low latency, and resilience under load. Collaborate across teams, mentor via pair programming and code reviews, and help drive backend architecture and engineering best practices.
