About

Crack the Backend is a content-driven technical website focused on backend engineering: Java core, JVM & GC, concurrency, Spring and microservices, databases and MyBatis, middleware (Redis, Kafka, RocketMQ, RabbitMQ, Dubbo), and distributed systems.

Purpose

The goal is to provide clear, practical explanations that help engineers understand how things work—not just how to use them. Content is written for developers who want to go deeper than tutorials and documentation.

Target audience

Backend and full-stack engineers, especially those working with Java and the JVM ecosystem. The material is aimed at developers who care about performance, reliability, and system design.

Maintainer

The site is maintained by engineers with hands-on experience in backend and distributed systems. Content is written in a straightforward way, without marketing language, and is intended to stand on its own as a useful knowledge base.
