Being Jeff

Hello, World

I have been building things with AI for a while now. At work, it is literally my job. But at home, in the evenings, I have been tinkering with something different. Something personal.

I want to build an AI agent that actually knows me. Not a chatbot that forgets everything between sessions. Not an assistant that needs the same context re-explained every time. Something that understands my codebase, my infrastructure, my preferences, and my way of working. Something that gets better over time.

I have no idea if this will work. The plan, if you can call it that, is to start with what I know: structured notes, markdown files, and an Obsidian vault full of everything I have learned as an engineer over the last fifteen years. Feed that into an AI, give it tools, and see what happens.

What this site is

This is a blog about the process. The real process, not the polished version. The wrong turns, the late nights, the moments where it clicks and the moments where it absolutely does not.

If this project grows into something worth talking about, I want to have written it down from the start. And if it doesn’t, well, at least there will be an honest record of what I tried.

Who I am

I’m Alex. Software engineer, nearly twenty years in. Based in Amsterdam. I work at a startup where I lead infrastructure and platform engineering. I have a homelab that is slowly taking over the house. I write in British English and I have strong opinions about code style.

That probably tells you enough for now.

What is next

I’m going to start with the wiki. An Obsidian vault of structured notes, covering everything from my deployment patterns to my debugging playbooks to my personal preferences. The idea is simple: if the AI already knows what I know, maybe we can skip the tedious part and get straight to the useful bit.

We will see.
