Introduction

I am Zhenguo Jin, a software developer with almost 5 years’ experience, and over 3 years of experience in developing scalable web-applications. I am currently working for JD.COM as a Senior Android Developer and Project Manager since 2014. I have a keen interested in the latest emerging technologies. I use my spare time to turn my experience, ideas and love for IT tech into informative articles, tutorials and more in hope to help others and learn more.

I love architecting systems in a high-performance environment with a focus on application development. My passion in Java and JavaScript is as strong as my believe in agile methodologies, especially Scrum. I decided to write this blog because, while there is plenty of information regarding application development in general, there is comparatively less information on styling and, in particular, theming apps. While much can be learned by browsing the app source code, this can be a fairly difficult process, and often it is not easy to find precisely what you’re looking for.It is assumed that the reader is familiar with application development in general.
