A 8-year Java architect sharing experience how to become an architect

Many programmers who work for a certain number of years feel that they have reached the bottleneck and do not know how to break through, in fact, this time will break through the legendary architect.

Architects are a very mysterious person, so what is the level of the architect's technology in general? How can I be called an architect?

In fact, can become an architect with the opportunity to have a great relationship, such as a programmer, the above has done, but the company did not give him the opportunity to do, a real framework of opportunity. Because before the architect does not leave, he will not have the opportunity, this is the reality!

Want to learn the latest Java technology, want to talk to the technical Daniel one-to-one exchange can add group: 744677563. Every night in the group, there will be a live video of Daniel explaining the latest technology, and there are free videos learning resources in the group.

People to middle-aged, technical people began to worry about themselves by the former wave on the beach, was "laid off", or "early laid off" is simply scared shivering ah!

The systematic study work needs is the basic knowledge, but is not to Baidu or the Google search data solves.

This helps to develop a more rational technical architecture, or to improve the inadequacy of the existing technology architecture, and to create synergies between the knowledge by correlating the relevant knowledge analysis after encountering problems. In order to let not do research and development of operations colleagues on research and development do not feel mysterious, can go to analyze the underlying causes of abnormal faults, I deliberately summed up a system of learning programs, this knowledge is systematically passed through a small program case to everyone.

To help you get out of this midlife crisis, take the path to a raise.

This time we recommend a free learning group 744677563, which summarizes Java distributed, High concurrency, JVM, high performance, microservices, blockchain, big data and other technologies, as well as interview resources.

The achievement of the great God is not a dream, or depends on whether you add
