Fabian Krumbholz

Fabian has spent 25 years building fast, accessible websites – and now shows developers how to get that same quality out of AI tools.

He has optimised web technologies from the moment they shipped, always obsessing over one thing: how fast a page feels to the person actually using it. And no era comes close to how exciting this one is.

The new Google tools will build you an excellent website or a shockingly bad one — the difference is knowing what good looks like. YouTube shows you the demos. Fabian teaches the setup that produces the golden ones: accessible, fast, and running in every browser.

He builds that way for a living, too. At Speed Kit he creates AI agents that automate web performance testing — production systems, not weekend prototypes — going deep on the tools that survive that standard instead of skimming fifty.

A Google Developer Expert for Web, Fabian has given 15+ DevFest talks across Europe and North Africa in the last two years. Generous people taught him this craft, and passing it on is a pleasure. You’ll find him talking with attendees before the talk, after it, and usually until someone locks the venue.
