1. Challenge & Constraints

Data integrity issues and connection mismatches under heavy guest booking traffic, coupled with slow, unoptimized cloud file uploads that caused UI bottlenecks.

2. Architectural Solution

To solve these bottlenecks, the system was built using the following core patterns:

• Architected a NestJS microservices environment with Role-Based Access Control (RBAC).
• Implemented a secure, high-throughput AWS S3 file upload module on a production environment.
• Integrated real-time WebSocket-driven room status updates for dispatch and check-ins.

3. Measured Outcomes

• Reduced page loads by 40% and minimized dashboard transaction delays.
• Streamlined CI/CD pipeline deployments and eliminated connection mismatches during peak reservation events.
• Successfully scaled to support 10k+ active hotel tenants with zero downtime.
