Preface:

Chen Lei, level P8, has worked in a famous first-line enterprise for many years. He is a core technology developer of the enterprise and has 13 years of development experience. Engaged in Java backend development, have deep research on distributed architecture, Spring micro services, MySQL, frameworks, Netty, JVM, performance optimization, and other technologies. Yes, small business or non-internet business 30K is unlikely to be a coder. There are also regional issues, which are not in my consideration, because apart from Beijing, Shanghai, Guangzhou, Shenzhen and Hangzhou, other places are also difficult to reach.

High salary is too common in BAT, generally senior engineer and senior engineer positions. It is about P6P7 in Ali, T5 in Baidu, T2-3 in Tencent, T3-1 in JINGdong, AND P6 in Meituan. I don’t know anything else. This level is their main coder level. They work overtime and can solve most problems. However, they still need to cultivate their ability of overall system architecture and in-depth analysis of bottlenecks.

An outline of the recommended learning path for architects

Part ONE: source code analysis

Introduce the classical design ideas used in the source code in detail, see how Daniel is to write code, enhance the technical aesthetic, enhance the core competitiveness.

Part TWO: Engineering

If you want to do a good job, you must first sharpen your tools. Whether it is a small white person or a senior developer, you need to choose good tools first to improve development efficiency and team collaboration efficiency, so that you have more world to think about.

Part three: Distribution

To meet the challenge of high-concurrency big data, improve the knowledge system from depth to breadth, and become the next Internet high-paying talent

Part FOUR: Micro services

Centering on the general mode of micro-service, the paper explains the common usage and principle of Spring Cloud, so as to make the development of micro-service more convenient and quick, and make the micro-service application more stable and available.

Part five: Performance optimization

From the underlying principles of JVM to memory optimization and then to the performance of each middleware tuning, do the most scientific and rigorous performance tuning

Part six: Concurrent programming

Understand the underlying principles, not just being a developer.

The above six knowledge systems are my experience summed up in the industry for many years, which are the most mainstream technologies at present. If you are interested in Java distributed, engineering, high concurrency, micro services, JVM and other technologies, you can add to my architecture group: 68-5167-672, which has Ali Daniel, we can share experience together.
