A production-ready app built with NestJS that acts as an intelligent bridge to WhatsApp via whatsapp-web.js. It exposes simple HTTP endpoints for triggering WhatsApp messages, while leveraging BullMQ and Redis for reliable message queuing and rate-limiting. A built-in WebSocket gateway provides real-time event publishing (e.g., QR Code generation, authentication status, and message receipts), providing a robust backbone for building enterprise-grade WhatsApp integrations.

A robust monorepo application built with Turborepo. It demonstrates the implementation of Domain-Driven Design (DDD) and Clean Architecture in a TypeScript ecosystem, ensuring the business logic remains decoupled from external frameworks.

Department Management System (DMS) - a modular NestJS API for managing users, courses, schedules, attendance, notices, activities, and reports. The project integrates with Auth0 for authentication and role management, exposes a Swagger/OpenAPI UI, and is designed for containerized deployment.
