Hi, I’m Christian Wittmann — SAP consultant, AI enthusiast, and traveller.
I work at the intersection of business software and intelligent systems, with a passion for technology, science, and exploration.
My online activities live across several platforms, each with its own focus.
This landing page links them all together.
AI & Technology
- Christian’s AI learning journey: chrwittm.github.io
Following the advice of Jeremy Howard, I started blogging about my learning journey. The main purpose of this blog is to explain and clarify concepts to myself through writing, my personal chain-of-thought, which is sometimes surprisingly difficult. - GitHub: github.com/chrwittm
Code, prototypes, and open-source projects. - LinkedIn: linkedin.com/in/chrwittm
I publish most SAP-related topics on LinkedIn. - SAP Community: profile.sap.com/u/chrwittm
Actively trying to give back to the SAP community. - Kaggle: kaggle.com/christianwittmann
Part of my learning journey in AI and data science. - X / Twitter: x.com/chrwittm
I enjoy the AI community on X and try to stay away from the drama.
Travel & Exploration
- Wittmann-Tours: wittmann-tours.de
From October 2017 to December 2018, my wife and I travelled around the world. We documented our journey and what we learned in this blog. - FindPenguins: findpenguins.com/chrwittm
An alternative to a full-blown travel blog.
I use this platform for posting photos, thoughts, and travel experiences from recent trips. - YouTube Channel: youtube.com/@chrwittm
Being an ambitious hobby photographer, I increasingly enjoy video.
My videos are mainly travel-related.
