URL Shortner

Microservices Architecture: Designed, built, and deployed a three-microservice platform (Spring Boot for URL, Node.js/TypeScript for ID/Analytics) to manage the full URL shortening lifecycle.

  • Distributed ID Generation: Engineered a fault-tolerant ID generation service using sharded PostgreSQL and transactional row locking (FOR UPDATE) to ensure unique, concurrent short code allocation.
  • Data Pipeline & Analytics: Established a reliable asynchronous click pipe using Kafka to push events to a ClickHouse data warehouse for fast, aggregated analytics and reporting.
  • Optimization & Security: Optimized URL resolution latency using Redis caching and secured the API using Spring Security with BCrypt hashing for user authentication.

Tech Stack: Spring Boot, Node.js, TypeScript, PostgresSQL, Redis, ClickHouse, Kafka, ClickPipe.
