About Me

Know Me More

Hello, my name is Jari-Hermann Ernst.

I am a TYPO3 developer from Berlin.

I have been working in the web environment for over twenty years now and have been a big TYPO3 enthusiast almost from the very beginning. Thanks to its open architecture and the almost unlimited expansion options that come with it, the system has allowed me to realise almost all the requirements that have been put to me during this time - from simple websites to a large intranet for several thousand users and connections to all kinds of other IT systems.

My playful curiosity and my approach of thinking in terms of the expected result mean that I am not just a pure coder. I like to bring my strengths in conceptualisation to projects. Experience and solution-orientation are my guiding values.

Why do I love TYPO3?
It's the combination of flexibility, openness, scalability and especially the active community.
