Hello,

My name is Zemian Deng, and this is my personal blog site. My interests are in software development and sharing knowledge. The first programming language I learned is C back in 1995. Since then I have spent 20+ years using various programming languages in different industries. I have spent major part of my career working with Java programming language and related technologies. In between I have also enjoyed using other scripting languages such as Python and Bash for automation and creating productive tools etc. Recently I have also gotten into Front-End development with JavaScript and NodeJS.

In general, I like to be pragmatic when it comes to software design. I think simple code makes less buggy software.

I use this blog as my personal journal to record tips and notes on what I have learned. Feel free to leave a comment below if you share the same interests. You will also find more about me through my LinkedIn profile and Open Source project contributions at my GitHub account.

My Programming Experience

I have worked with quite of few programming languages and related technologies in the past. While some experiences are more extensive than others, but I will only mention ones I actually have worked with in my past. Some tools and frameworks are already obsolete, while others I am no longer actively using. But I have worked with these at one point in my past, and I have attained ranging from proficient to expert level with some them.
