Shortify: High-Throughput URL Shortening Engine

Key Features

  • Architected a Multi-Layer Caching system utilizing L1 LRU Memory and L2 Redis to achieve average redirect latencies of 7.12ms.
  • Developed a custom Token-Bucket rate-limiting algorithm at network ingress to throttle concurrent requests and protect against traffic spikes.
  • Implemented on-the-fly Base64 QR code generation during URL ingestion, eliminating persistent storage overhead for image assets.
  • Benchmarked using k6, achieving a 100% success rate across ~7,000 requests under 50 concurrent virtual users.
