My name is Hans-Peter Lehmann and I am studying IT in Germany. Because I am developing Android apps since 2011, I am quite experienced in this field. My apps on Google Play have more than 700,000 downloads from all over the world and I contribute to multiple open-source applications (view on GitHub or GitLab). I also worked for various companies to develop Android apps. Additionally, I compile and modify the Android system to get an insight on how the whole system works.
Furthermore, I develop complex and feature-rich websites and databases for various purposes as well as Java and native applications for PC. Some of my current projects can be found on my private website, www.hanspeter-lehmann.de.
