✍️ By Abhishek Kumar | #firstcrazydeveloper Microservices Architecture Leads to Chaos — Unless Designed Right Microservices are like independent puzzle pieces of a large system — each one performs a specific task, communicates through well-defined APIs, and can be deployed independently. When done right, microservices enable rapid scaling, continuous delivery, and fault isolation. But when…

✍️ By Abhishek Kumar | #FirstCrazyDeveloper Apache Kafka is a distributed event streaming platform that powers some of the largest data-driven applications in the world. From Netflix’s recommendation engine to LinkedIn’s activity feed, Kafka has become the backbone of real-time data pipelines and event-driven architectures. But what exactly makes Kafka so powerful? Let’s break it…

✍️ Abhishek Kumar | #FirstCrazyDeveloper APIs are the backbone of modern applications, enabling different systems, services, and devices to communicate seamlessly. Over the years, several API protocols and communication styles have emerged, each suited for specific use cases — from mobile apps fetching user data to IoT devices streaming sensor events. In this blog, let’s…

✍️ Abhishek Kumar | #FirstCrazyDeveloper When building large-scale systems, the challenge isn’t just about writing clean code—it’s about designing for scale, resilience, and performance. This is where system design heuristics come into play. They act as guiding principles to make smart decisions when architecting software. In this blog, we’ll break down 15 key heuristics, explain…

by Abhishek Kumar | FirstCrazyDeveloper System design interviews often go beyond “How would you scale this system?” — they test how deeply you understand scalability, consistency, fault tolerance, and efficiency. Behind almost every modern distributed system — whether it’s Google Search, Netflix streaming, Amazon DynamoDB, or Git — lies a set of fundamental algorithms and principles.…
