ArchiTech Intranet

Challenge: Create a robust bidirectional synchronization between WooCommerce and the intranet that handles orders, users, subscriptions, and permissions without errors or duplicates.

Solution: I developed a webhook system with NestJS that listens to WooCommerce events, processes orders in real-time, automatically creates service contracts, assigns permissions based on service type, and activates user accounts. I implemented retry mechanisms, detailed logging, and data reconciliation to ensure consistency.

Challenge: Automatically synchronize the architects' local working directory with AWS S3, detecting changes, avoiding duplicates, and maintaining folder structure.

Solution: I implemented a synchronization system with change detection based on file hashes, modification metadata, and state tracking. The system detects new files, modifications, and deletions, replicates the directory structure in S3, and maintains a record of all operations for auditing.

Challenge: Design a scalable architecture that supports multiple roles with granular permissions, real-time communication, and heavy document management.

Solution: Modular architecture with Angular for the frontend (standalone components, lazy loading), NestJS with domain-driven architecture for the backend, PostgreSQL with Prisma for data management, BullMQ for heavy work queues, Socket.io for WebSockets, and AWS S3 for scalable storage. I implemented authentication guards, role decorators, and access policies at the controller level.
