Now the salaries of Java-related positions are getting higher and higher, and the increase is getting bigger and bigger.
You can view the data through the job-friend collection. Taking Java-related jobs in Beijing as an example, [20k-30k] Java engineers with salaries accounted for 30.8% of the total practitioners!
Beijing Java Engineer "Salary Income Level"
If you are in a small or medium-sized company, in fact, around 20K is almost the limit, and it is very difficult to continue to raise your salary. The Java technicians at the P7 level of Alibaba, the salary can easily reach 30K-50K, which does not count as shares and year-end bonus.
But is it really difficult to become a P7 programmer at Alibaba? In fact, it may not be.
Everyone knows that the senior technical expert of Ali P7 is basically the highest rank that can be achieved by front-line technicians, and is also the goal pursued by many programmers. Reaching the P7 Java senior architect level of one million a year, not only must have excellent programming skills and system design capabilities, but also have a deep accumulation in terms of technical vision and business insight.
Recently, the technical veteran soldier invited his friend who is an architect in Ali to sort out a copy of xmind-"Technical Stack Required by Java Senior Architects". Reference and reference in the learning direction.

The above is a summary graph of the architect system learning. Every technical knowledge will also have expanded content. Programmer friends who need to watch the complete knowledge graph to check for gaps can fill in the backstage private message reply [Graph] to get!
