Drawing from two decades of scaling community-driven platforms, he is known for maintaining core TYPO3 extensions and co-authoring the O’Reilly TYPO3 Cookbook. Before focusing on AI infrastructure, he solved heavy integration problems at enterprise scale for Deutsche Telekom. Today, he works to keep complex systems from spiraling out of control. His talk on [speeding up the wrong things](/videos/1930-a-true-story-about-speeding-up-the-wrong-things) breaks down why AI integration often leads to unmanageable chaos. He advocates for strict governance, observability, and reducing connections rather than endlessly generating new ones. ## Past Sessions ### World Congress 2026 Europe - Virtual Stage · June 30, 2026 Online - [A True Story About Speeding Up the Wrong Things](https://www.wearedevelopers.com/videos/1930-a-true-story-about-speeding-up-the-wrong-things) · 🎥 Watch recording ## Videos - [A True Story About Speeding Up the Wrong Things](https://www.wearedevelopers.com/videos/1930-a-true-story-about-speeding-up-the-wrong-things) · Jo Hasenau, Petra Hasenau ## Links - [X](https://x.com/bunnyfield) - [LinkedIn](https://www.linkedin.com/in/jo-hasenau-38a7b615b/)
