# 个人介绍邮件

My name is Xie Yanbo, a Chinese engineer with 20 years experience in software development. I'm looking for job opportunities in Germany, including senior engineer, technical lead positions in web development, SRE, and machine learning infrastructure.

I'm experienced in developing high performance web site. At the same time, improving code quality, unit testing, code refacotring, CI and CI have always been areas of interest to me. Now I'm working at one of the top 4 AI companies in China as a technical leader in building infrastructure for machine learning, which I think would help in building machine learning models as well.
