“We host in Frankfurt, so we’re GDPR-compliant.” The sentence comes up in almost every conversation about Vercel and Supabase, and it is half the answer to a question that has two halves. The region answers where the data lives. It does not answer whose law applies to the companies that process that data. This article … Read more
For most web applications, the cookie banner question comes up too late. The application is built, an analytics script is in, the login page comes from a cloud service, and suddenly the very first page view needs a consent dialog that nobody planned for. The DI² project turned the question around. GDPR without a cookie banner was … Read more
A Claude Code session opens a Git repository with no pending changes, works for half an hour and commits whatever has changed at the end. Run alone, that is correct. As soon as a second session or a human works in the same repository, the very same routine can pull someone else’s work into the … Read more
Since spring 2026, two projects have been taking shape with the same coding agent: an ETL generator on Next.js and PostgreSQL, and this blog. The agent does not complete lines, it works through assignments in the repository. This article collects my agentic coding experience from a user’s perspective. I build databases, ETL processes and the … Read more
The conventions were settled: procedure skeletons, DECLARE banners, file naming, forbidden constructs — all versioned in rule files, every rule with its rationale. The only open question was which tool should check the SQL conventions. And the first reflex was the same one that probably surfaces in every Postgres team with convention ambitions: “Just use … Read more
There is a moment when a CLAUDE.md tips over. That moment does not sit on any calendar, it shows in behavior: the file keeps getting longer, and the rules inside it keep getting followed less. Every new convention you write in dilutes the ones already there. That is exactly where the project behind this article … Read more
It didn’t start with an audit. It started with a nagging feeling: the interface looked restless. You don’t notice it at first glance, but on the second and third look it is there — a timestamp slightly larger here than there, a dialog title a touch smaller than in the neighboring dialog. Everyone knows the … Read more
“You spend more time with her than with me.” That’s a sentence you usually hear when an affair comes to light — in my case, it was about Claude Code. And suddenly there was a question in the room I had never thought about before: Is Claude actually a woman or a man? What this … Read more
An empty repo and Claude Code, Anthropic’s coding agent in the terminal — that’s all it takes to get going. And that is exactly the problem: the model writes code immediately, but by default nothing ensures that a specification exists first, that a review happens afterwards, or that the database schema deploys reproducibly. A Claude … Read more
Every new project starts with the same ritual: create an empty repo, then hunt down the folder structure, the conventions and the workflow files from the last project — and forget half of them. A Claude Code project template can invert that reflex: instead of starting with nothing and building up piece by piece, you … Read more
