Zhangjian /ʒɑŋ dʒi:ˈɑ:n/
I'm an experienced software engineer focused on coding, software engineering, and system design.
I maintain and contribute to open-source projects, including Apache BookKeeper, Apache Pulsar, openGemini, and ApolloConfig. I also build software projects, libraries, and tools, and write about software, systems, and technology.
Currently, I work on intelligent data decision platforms at Huawei Cloud.
