About Leo

Hey, my name is Leonard Pahlke, and I am a software engineer with a focus on cloud, open source and sustainability. I like to build systems that tend to get big and complex. I am a CNCF Ambassador, Chair for the CNCF TAG Environmental Sustainability, Emeritus Advisor for the v1.28 Kubernetes release, lead the Kubernetes release team for v1.26 and organize meetups in Hamburg. I am currently working on my open source project called Carbonaut.

I think that thanks to computers, we are in the process of digitally transforming every business, and now in the middle of the transformation we are again challenged to rethink everything and incorporate sustainability in all aspects. We are on the way to inventing a sustainable and digital economy, and we have to be careful not to lose touch with each other and the world in this journey.

Am Meer, am wüsten, nächtlichen Meer

Steht ein Jüngling-Mann,

Die Brust voll Wehmut, das Haupt voll Zweifel,

Und mit düstern Lippen fragt er die Wogen […]

Es murmeln die Wogen ihr ew’ges Gemurmel,

Es wehet der Wind, es fliehen die Wolken,

Es blinken die Sterne, gleichgültig und kalt,

Und ein Narr wartet auf Antwort.

von Heinrich Heine, Die Nordsee: Fragen
