Interesting Thoughts on Frontend and Backend Engineering

While reading other people’s blogs recently, I came across several interesting points that made sense to me. I’m keeping a record here.

1. Expectations for backend engineers

Focus on Java fundamentals, design patterns, JVM internals, Spring and Spring MVC concepts and source code, Linux, MySQL transaction isolation and locking, MongoDB, HTTP/TCP, multithreading, distributed architectures (Dubbo, Dubbox, Spring Cloud), elastic computing architectures, microservices architectures (Spring Boot + ZooKeeper + Docker + Jenkins), Java performance optimization, and related project management.

Backend engineering focuses on the “three highs”—high concurrency, high availability, and high performance—along with security, storage, and business logic.

For frontend engineers:

Focus on HTML5, CSS3, jQuery, AngularJS, Bootstrap, React, Vue.js, Webpack, Less/Sass, Gulp, Node.js, Google’s V8 engine, JavaScript multithreading, modularization, aspect-oriented programming, design patterns, browser compatibility, and performance optimization.

Frontend engineering focuses on presentation, smooth and responsive interactions, compatibility, and user experience.
