I build
with Claude.


More and more people ask me how I work with AI. Instead of repeating myself, I document everything here: my method, my config files, my projects, and the details of what I'm building — session by session.

How I use Claude

Read the full guide →

My method comes down to a handful of .md files I drop into Claude's "Project Instructions." A main CLAUDE.md that defines my tone, my rules, and my context; extension files loaded on demand (strategy, dev…); and a dedicated file for each brand's DNA.

The guiding principle: Compound Engineering. Every time Claude gets my style wrong, I add a rule. The system improves with use — and all future work benefits from it.

Alongside the journal, I publish clear guides on AI and the tools I use: what it is, what it's for, what it changes. Written for busy merchants and decision-makers, but readable at any level — three reading depths on every page.

The first one lays the groundwork: generative AI and "LLMs", jargon-free, covering the major players and — most importantly — what they can't do.
