For programmers who have been developing for one to five years, start by asking yourself a few simple questions:
- You’ve been working for a few years. Do you want to be a simple programmer all the time?
- Would you like to keep writing code and not care about anything else?
- A project’s early requirements, design, deployment and maintenance, the leader came to you, you said I can’t handle, ok?
Programmers are not machines that type code. In the first year, you don’t know too much. You can do whatever your boss tells you to do.
But the second year, do you still want that? Impossible, one year of experience you can go into the industry, it’s time to learn how to do requirements analysis, how to design databases, how to write all kinds of documents, how to write better code? This is a requirement for advanced programmers!
What is the standard configuration for an advanced programmer? Answer: monthly income 30K!
What is an advanced programmer?
Has the analysis design ability, can carry on the technical breakthrough, and has some industry deep background programmer!
After a project is set up, you should actively participate in the preliminary design, thinking and analyzing problems together with old comrades, learning experience! OK, you’re growing up now!
In your spare time, you must remember to learn more. Practitioners in any industry need to keep learning. Only by working with higher efficiency can you create higher value. Especially for programmers, a careless may not be more on the pace of The Times, every day the Internet winter, in fact, what winter, just lazy excuses! Don’t take the initiative to learn, waiting for you, only be eliminated!
What are the levels corresponding to 30K?
The monthly salary of 30K is quite common in BAT and other first-line big factories. Generally, senior engineer or senior engineer positions are p6~ P7 in Ali, T5 in Baidu, T2-3 in Tencent, T3-1 in JINGdong and P6 in Meituan. I don’t know about others.
So what should Java programmers who have been working for 1-5 years learn to jump ship and get paid?

Conclusion:
Due to limited space, the content of the Internet P8 Architect Technical Map is presented in the form of screenshots, but the full original PDF is 100% free to share.
It’s true that technology is changing rapidly these days, but it’s not true that “programmers of a certain age can’t keep up with the younger generation in terms of creativity and learning ability.”
At the moment, many people are confused by the perception that Java developers are not easy to find jobs. Some people mistakenly think that the market is saturated, but they do not consider that it is their own lack of ability, and they tend to be like this in the process of learning:
- Expect to chew through a book, a set of videos to watch, more knocking to write some can be done;
- Learn everything, feel like you can do everything, but feel confused when working on a project;
- Listen to others say which good school which, blindly follow the trend;
- All kinds of messy things are used, as long as the effect of other can be ignored, stay in the “handling” stage;
- Never aware of the norms and standards and considerations of doing a project;
- It can be imagined that the skills learned in this way can not reach the level required by the enterprise, and naturally can not find a job.
In this side, xiaobian is sharing an Internet P8 architect technical map, small friends can according to the map of knowledge points, control their own technology to check the gaps.
At the same time also provides free Java architecture learning materials, learning technology content includes: Spring, Dubbo, MyBatis, RPC, source code analysis, high concurrency, high performance, distributed, performance optimization, micro services advanced architecture development and so on.
