Self-introduction：• My value lies in rich experience in many different domains in past 16 yesrs career, which I think is one of key factors of any kind of application (or technique) support work. I had following experience more or less: 4G core network, Telecom SDH optical network, cloud,Python , MySQL, TCP/IP network, linux application support, IT helpdesk level 1, level 2, windows system management. If making a viewpoint switching, my experience covers automatic test coding, security awareness, oversea onsite integration, hardware installation, core network technical support, upgrade, project management, potential issue analysis, shell and python script making. Detail can be found in ‘Work Experience’ part. Those experience enable me to know at least the way of work in domains that I even don’t serve, such as software development, remote technique support. • Also, my value lies in 6 years experience of 4G core network support in Ericsson. As core servers of 4G mobile cell phone, the core network nodes integrate many techniques of different domains: telecom, security management (authentication, authorization, and accounting), database, TCP/IP network, linux system. Although we focus on integration of those techniques, I got background of them anyway. That is why I think my experience of 4G telecom support could be transplanted to many other applications support based on linux/Unix platfrom.• My value lies in my personality of rigor and enthusiasm. My system test work and upgrade work can reflect how I am careful with some risky works. And I am always enthusiastic to the new techniques and unknown issues.
