I am Jan Thielemann.

What I Do

Over the past few years I worked on:

Mobile Apps

I design and develop mobile applications for iOS and Android.


I administrate, customise and optimise websites.


I develop backend software for various systems and purposes.
You have a great idea but don’t know where to start? I can help you by designing sketches, banners, covers, mockups and more.
Search Engine Optimization
I can identify problems with your websites, research keywords and monitor your rankings.
Web Design
I build websites from scratch and re-design, optimize and customize existing websites. I can also take care of the administration.
App Development
I worked as a part of a bigger development team but also completely independent to create mobile applications for iOS and Android.
Content Creation
I can help you with SEO by creating custom, keyword optimized content for you.
New Technologies
I love learning and I love what new technologies make possible. You want to start something new? Get me on board!
