System Design Series - Finale 🎉

First, a big thank you.

4 months ago, Started sharing
Tech content from my learning and work experience.

In mid March, I started this series with just over 1000 followers.

Today, as we close Week 10,
we’ve crossed 4,700+ followers 🚀

What started as a simple idea, sharing one
System Design topic every day turned into something much bigger.

10 weeks. 10 topics. 40+ posts.
One complete Backend System Design series Production Ready.

Here’s everything we covered the foundation every backend engineer needs:

Week 1: APIs & Databases — REST, SQL vs NoSQL, indexes, pagination

Week 2: Caching — Redis, cache invalidation, CDN, multi-layer caching

Week 3: Message Queues — RabbitMQ, async processing, retry patterns

Week 4: Load Balancing — Algorithms, horizontal scaling, stateless design

Week 5: Microservices — Monolith vs microservices vs modular monolith

Week 6: Database Scaling — Read replicas, replication lag, failover with Patroni

Week 7: API Gateway & Rate Limiting — DDoS protection, circuit breakers, strategies

Week 8: Monitoring & Observability — Metrics, logs, traces, alerting

Week 9: Security — OWASP, authentication, encryption, common vulnerabilities
