    I have 6 years of experience in front-end (vue, html, js, css), java (spring), etc. My previous team was less than 50 people, I would help some newbies point out problems or fix bugs in their code, and I had solved many difficult problems for my team. so My skill is not only in js or java: * reviewed code for Android and IOS in order to solve the webview problem. * built and deployed tools such as strongSwan in order to solve the problem of local machine and test environment access each other. * built and deployed applications such as ELK, jenkins, nexus, git, docker in order to devops. * learned to modify the relevant code of Golang and Java in ELK system, in order for it can show the calling relationship of Dubbo framework and store the k8s pods stdout log propperly. * used some tools in Linux in order to solve network or deployment problems. and so on... Finally, although I have been reading a lot of English materials for the past few years in order to solve those problems, my spoken English still lacks practice. I can improve it well in this platform if needed. I believe I can do it because so many difficult problems have been solved by me.
