How I built this site

Practicing what I preach: an AI-first build, a minimal codebase, no cookies, no trackers — and a design system that’s easy to evolve.

01 / approach

The approach

I started the way I’d start any product: with research. I collected personal sites I admired, broke down what made each of them work, and turned that into a design direction — a mono font for the nerdy bits, a display font for the headlines, one bold accent color, and animations in homeopathic doses.

Then I built it AI-first with Claude Code: from the research through scaffolding, components and copy, reviewing and steering along the way. The whole site is a handful of data files, a dozen small components and zero dependencies beyond the framework — built as a one-time shot that’s cheap to maintain.

Everything is static HTML. The only JavaScript shipped to your browser is the theme toggle, the mobile menu and a tiny scroll-reveal observer. There are no cookies, no analytics and no third-party requests at all.

02 / the brief

The prompt that started it

AI-first doesn’t mean typing “make me a website”. It means doing the thinking up front and handing over a brief precise enough to build from. This is the actual kickoff prompt I gave Claude Code — content structure, reference sites, constraints and the task itself, typos and all.

After the first build I spent another two to three hours fine-tuning the content — the words, the examples, the order of things — but never touched the design, the structure or the components again. That’s the real test of a foundation: it held.

## Contact
## Footer
- Imprint
- Basic Data privacy: we will not use any trackers, cookies, etc. so very simple German law privacy statement
- How I built this site, with an explanational blog content, how I approached it, the exact tech stack with backlinks to the resources as well as a backlink to all those website I mentioned below
# Header: LinkedIn, Github

# Example Pages for Reference
A handful of personal sites I admired — analysed for what made each one work,
then distilled into one design direction.

# Constraints
- Preferred tech stack: Vue with Tailwind as I am skilled with these
- A static site generator framework like Astro or Hugo if it brings value
- I do not want to use any component libraries, as I would like to keep things easy to main
- I will probably only add some pages over time, it will mainly be a one-time shot and then bugfix
- While the page is mostly about the final website, I love great code. Please follow all best practices of the frameworks and libraries we choose. For this project, I would love a simple and minimal codebase with some smart usage of Frontend components, etc.

### Your Task:
- Research the all given links, understand the similiarties and differences
- Ask back questions if you are in doubt or need more clarification
- We will most probably not meet my design in the first place. The design system should be flexible to update, be based on real standards
- Tell me upfront, what type of contents (like images, etc.) you need
- Implement the website as Senior Frontend Architect
- Build it the way it's easy deployable with Github and cloudflare static pages
- Run it locally, see it in action and fix bugs that occur
- Then switch the role you have:
    - You act as a Tech recruiter or Team lead and you are interested in the candidate
    - Think about the content of the page from this angle and suggest some updates
