URL Shortener + Analytics 🔗

Designed and developed a production-grade URL shortening platform that transforms long URLs into secure, shareable short links while providing powerful real-time analytics and performance insights. The platform enables users to create custom short URLs, monitor click activity, analyze visitor behavior, and manage thousands of links through an intuitive dashboard. Built using a cloud-native, event-driven architecture, it delivers high availability, low-latency redirects, and scalable analytics processing for enterprise-scale applications.

🧑‍💻 What I built: • Generate secure and unique short URLs • Custom aliases and branded short links • Real-time click tracking and analytics • Geographic and device-based insights • Browser and operating system analytics • Referrer and traffic source tracking • QR code generation for every short URL • Link management dashboard • Search, filter, and organize links • REST APIs for seamless integration

🧠 Engineering Highlights • Implemented high-speed redirects using Redis caching • Asynchronous analytics processing with Apache Kafka • Designed a scalable event-driven architecture for millions of requests • Optimized database performance with indexing and query tuning • Secure authentication using Spring Security and JWT • Built RESTful APIs following clean architecture principles • Cloud-ready deployment with Docker and AWS • Enterprise-grade architecture focused on scalability, reliability, and maintainability
