Hello I’d like to clarify the backend scope for the **Hotel Automation Platform** so we’re aligned before starting. Main Responsibilities: 1️⃣ Webhook Processing Receive bookings from **Channel Manager (Account A)** via webhooks and process them in an **event-driven** way to prevent duplicate processing if the same webhook is received more than once. All events should be logged in **AutomationLogs / SystemLogs** for traceability. 2️⃣ Automation Engine Apply rules to each booking, such as: * Commission deduction * Price adjustment (seasonal or promotional) * Additional fees (e.g., cleaning fee) * Guest data adjustments if needed 3️⃣ Virtual Card Service Generate a **Virtual Credit Card (VCC)** for each booking and link it to the booking record. The system should be ready to integrate with the chosen card provider API. 4️⃣ Integration with Account B & PMS Send the processed booking to **Account B** via API and ensure synchronization with the hotel **PMS** so the final reservation reaches the hotel correctly. 5️⃣ Database (MongoDB) Design the main collections such as: Users, Properties, RoomTypes, RatePlans, Listings, Bookings, Guests, VirtualCards, AutomationLogs, SystemLogs. 6️⃣ API Endpoints Webhook Endpoints: POST /webhook/new-booking POST /webhook/modify-booking POST /webhook/cancel-booking Internal APIs: GET /bookings GET /listings POST /virtual-cards POST /automation/execute 7️⃣ Scalability & Logging The system should comfortably handle around **100–200 bookings per day**, with full logging and proper error handling across services.

When bookings arrive from your channel manager, the last thing you need is a tangle of duplicate webhooks or missed logs, especially when every reservation must flow smoothly from automation to PMS. Not knowing if data is fully tracked or if rules like commission and price adjustments are applied correctly can quickly become a costly headache. With a streamlined backend, you can count on every booking being processed once, logged for full traceability, and routed exactly where it needs to go. You will see bookings sync from channel manager to PMS with all automation and virtual card handling fully integrated. I will set up webhook processing to prevent duplicates, build the automation logic for your booking rules, and ensure clean API integration with Account B and your PMS. Would you like to discuss the automation rules you want to prioritize first?

Hello, I’ve gone through your outline for the Hotel Automation Platform, especially the need for event‑driven webhook handling and clean integration with Account A, Account B, and the PMS. I’ve built similar automation pipelines where I delivered deduplicated event processing and full system logging to maintain traceability under high booking volume. I see the deeper challenge here being state consistency across four systems: channel manager, automation engine, VCC provider, and PMS. A junior developer often misses idempotency rules, booking state transitions, and timestamp ordering, which are critical to avoid double‑charges and duplicated reservations. I’ll design isolated services for webhook intake, automation logic, and VCC generation, using MongoDB change‑streams and structured logs to ensure reproducible flows. I’ll implement booking normalization, pricing rule execution, and downstream synchronization with Account B and the PMS through versioned API calls. To keep the system maintainable, I’ll document each internal endpoint and set clear retry logic for API integrations. Next step is confirming your preferred environment and deployment setup. Thanks, John allen.

Hello, I see you need a backend developer to build a Hotel Automation Platform with a focus on webhook processing, automation rules, virtual card generation, and integration with multiple accounts and PMS. Your emphasis on event-driven processing and detailed logging for traceability stands out as a critical part of the system. You want a robust solution that handles webhook events from Channel Manager (Account A), applies complex business rules like commission and fee adjustments, and generates virtual credit cards linked to bookings. The design must also sync bookings with Account B and the hotel PMS, while managing data in MongoDB collections such as Bookings, Guests, and Logs. The API endpoints for webhook and internal services must be reliable and scalable for 100–200 bookings daily. I have built backend systems using Node.js and MongoDB that process real-time webhooks with idempotency to avoid duplicates, implement complex business logic, and integrate with third-party APIs, including virtual card providers. I designed similar scalable logging mechanisms and well-structured collections for bookings and user data, ensuring seamless synchronization with external systems. I can deliver a working backend aligned with your requirements within 10 days. Let’s discuss how to start and ensure the system fits your exact needs.

Hi, Your architecture for the Hotel Automation Platform makes sense, and I’d build it using an event-driven backend to ensure webhook reliability and prevent duplicate booking processing. Incoming webhooks would first enter a queue system (Redis/RabbitMQ) where each event is logged and processed safely with idempotency checks. The automation engine would then apply rules such as commissions, price adjustments, and additional fees before generating a Virtual Credit Card (VCC) through a dedicated service ready for provider API integration. After processing, the system would sync bookings to Account B and the PMS using a reliable integration layer with retry logic. For the backend stack, I recommend Node.js (NestJS) + MongoDB + Redis, which works well for scalable event processing and logging. The system would include the collections and APIs you described, along with proper indexing, monitoring, and error handling to easily support 100–200 bookings per day. I can also provide a clear architecture diagram and database schema before development so we’re fully aligned before implementation begins.
