URL Shortener Service

Developed a production-ready URL shortening backend service that enables users to create, manage, and track shortened URLs through a secure REST API. The system supports custom short codes, click analytics, URL management, and high-performance redirection while providing a complete authentication ecosystem including email verification, JWT-based access and refresh tokens, token rotation, password reset workflows, and secure logout mechanisms. Built with Node.js, Express, TypeScript, PostgreSQL, and Drizzle ORM, the architecture follows a clean separation of concerns through controllers, services, validations, and middleware layers.

The resulting platform provides a reliable and secure URL shortening infrastructure capable of handling authentication, link management, analytics tracking, and redirection workflows within a single backend service. The layered architecture and TypeScript-based codebase improve maintainability, scalability, and developer experience, while security measures such as token rotation, input validation, and rate limiting significantly reduce common attack vectors.
