I Built a URL Shortener Like a Real System (Sharding, Caching & More)

In this video, we go beyond the typical system design interview question and actually build a working URL shortener the kind that could run in production. Instead of just whiteboarding concepts, we dive into real code, architecture diagrams, and scaling techniques like sharding, caching, and unique ID generation. We also stress test both the strategies and see how they fare against collisions.

We cover:

✅ What makes a real-world URL shortener scalable
✅ Designing for performance with Redis caching
✅ Sharding databases to distribute traffic
✅ Generating short URLs with nanoid library
✅ Step-by-step walkthrough of the codebase
✅ Architecture breakdown and request/response flow
