Welcome

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 / Twitterx.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.
