Why this site exists

I write this page to collect my thoughts, and I hope it is useful for others too. There is a lot of smoke around building things with AI right now. I do not mean that negatively: the field moves fast and I learn something at every meetup. But what helps, every time, is going back to a few basics and having a structured understanding of how the pieces fit.

I believe the quality of your learning sources matters more than ever. I went back to learning from fewer sources and fewer people, and I recommend that to everyone. This site is not necessarily the best source for you. It is useful mostly if you are about to start building with AI, or you have started but you do not come from a technical background and keeping up is a problem because you do not have much time. I do not have much time either. That is why I stay structured.

How current is this

Everything is moving fast. Something that needed a complicated workaround three months ago may work out of the box today. I review these pages often, and if you think something is outdated, tell me on LinkedIn. Principles matter more than the latest things, though, and most of what is here is about principles.

Working with me

Besides the free material, I also take on paid work. I advise companies on AI, LLM visibility and marketing, coach people one to one, and run workshops that get teams working productively with tools like Claude Code.

The simplest way to reach me is a direct message on LinkedIn. X works too.
