Built a complete URL shortening platform with analytics, expiry handling, and secure email-based authentication in a weekend practice sprint

Problem

The main challenge was implementing a reliable short-link redirection system that could securely resolve shortened URLs, track analytics, and handle inactive or expired links gracefully without breaking the user experience.

Solution

Implemented a redirect flow where short URLs first route through the NanoCut application, validate the link state, record analytics data, and then redirect users to the original destination URL. Added fallback handling for expired or inactive links along with secure email-based login using Resend and JWT authentication.

Overview

NanoCut v2 is a modern full-stack URL shortening platform built with the MERN stack, focused on secure link management, analytics tracking, and customizable short URLs. The application combines a clean React frontend with a scalable Express and MongoDB backend, providing fast redirects, authentication, and reliable analytics handling.

Results & Impact

Successfully built a production-style URL shortener within a weekend practice project, improving understanding of redirect systems, authentication workflows, analytics tracking, and scalable backend architecture.
