It has been nearly five years since I graduated from college. Every time I talk about my career path, I feel grateful for escaping from my comfort zone. I was born in a non-211 or 985 university, and after graduation, I joined a small Internet company. As an ordinary entry-level engineer, I often encountered challenges during my work, but my skills were always limited to the surface. When I encountered some difficult practical problems, I had no way to start or get in touch with large projects.

Such a life lasted for three years. Due to the limitations of the company platform and the lack of my own ability, I gradually lost my fighting spirit and lived a precarious life in this company. At the same time, I felt very uneasy because of the uncertain future.

It is said that three years is a hurdle for programmers, whether to promote or improve their core competitiveness, these years are very critical. One day, I happened to see a post about the experience of Spring leaders, telling about the detour he took when he first entered the circle and how he finally entered Kuaishou to achieve a counterattack.

Following the big guy’s ideas, I analyzed my own actual level and situation:

1. The technology is not precise and systematic: the technical ability is superficial, and I do not know the underlying logic and architecture, and I do not know how to systematically learn;

2. Encountered career bottleneck: standing at the watershed of the 3-year career, without sufficient comprehensive ability, I can only be eliminated if I want to raise my salary due to lack of technical strength;

3. Interview is not competitive: Not from prestigious universities or specialized courses, want to enter a first-line large factory, but there is no reply after each interview, and the job-changing plan always fails;

Then, based on the recruitment needs of big factories and the experience shared by the big guys in the post, I listed 9 abilities that need to be improved. If you are as confused as I was, I suggest you read them too:

Of course, I know it is not easy to learn and master these abilities. It requires a high degree of self-discipline and a lot of learning time. Usually, the work is very saturated, so if you go to self-study blindly, you will probably take a detour and consume a lot of time and energy. If there is no system for learning, no effort will be wasted.

According to the above promotion ideas, I found a learning route, which is also a major contributor to my small goal of entering dachang 40W +.

Framework source code:

A technology just can use nothing, only skilled is useful, with a technology encountered problems how to solve quickly, the general ability to solve problems can directly reflect your comprehensive ability. Learning to build a wheel is an important part of becoming a qualified architect, so how to learn to build the wheel, here are the learning methods I have organized for you.

Learning the basics of source code is best to have a basic understanding of the framework, if you are already familiar with that is the best.

Concurrent programming:

Concurrent programming is not as difficult as we thought, most of the time we did not get the point of concurrent programming when we were thinking, most of the time we were confused to learn concurrent programming, it was difficult to understand what concurrent programming should pay attention to, during this period, I felt that I took a lot of detours.

Performance tuning:

Java performance tuning is a headache for many developers. Why? Today, a simple system consists of applications, databases, containers, operating systems, networks, etc., and any performance problem that occurs online may require you to coordinate multiple components to optimize. There is a clear learning curve for how to easily tune Java performance.

Distributed framework:

A distributed framework is the same service that sets up different parts of a database on different servers. To relieve the pressure of massive data access to the database. Many large companies have large business volume, and the daily page view reaches millions or even hundreds of millions. In the case of small page view, it is possible to improve the configuration of a single server to meet the demand. But when a single server can no longer meet the needs of the need to do distributed processing. After all, a server’s processing power is limited. So now many large factories for distributed requirements are very high.

The service:

Microservices architecture is a way of replacing the development of a single large application with a handful of microservices, each running in its own process and communicating with a lightweight mechanism, usually HTTP RESTful apis. Micro service emphasizes small and quick, any relatively independent function service is no longer a module, but an independent service.

For example, the former large corps of fully functional troops will be broken up into specialized units, each with its own responsibilities, each fighting for its own, and communicating with each other through clear interfaces.

Actual project:

As a qualified architect, in addition to master the senior solid framework foundation, you also need to be experienced in large-scale project combat, able to lead the team, complete the project combat, the following to give you a list of two front-line Internet big factory project combat. (Double Eleven E-commerce platform and distributed call chain platform)

Conclusion:

The above learning route is based on years of experience summarized architecture, I hope to have some help for everyone’s learning, just for reference, need this learning route more in-depth details and hd version, you can forward the article, pay attention to the following public number to obtain ha

Finally, for the sake of jin Jiu Yin ten, I also prepared a big factory interview question (including analysis). I hope you can get your offer in this period of time. How to obtain information: pay attention to the public account below.
