The Portfolio Problem

Every developer needs a portfolio site. Most are either boring (standard template) or overengineered (React for three static pages). I wanted a site that shows what I can do without becoming a maintenance nightmare itself.

"I also wanted a place for my blog, for case studies, for freelance inquiries. A central hub. And the ability to showcase my Claude AI workflows in practice."

The site you're on right now. My digital storefront. Built with Rails 8, Hotwire, Tailwind CSS, and a fully automated Claude AI content pipeline. Bilingual (DE/EN), SEO-optimized, self-hosted on my own server. Blog posts are generated with Claude and go through a multi-stage review process.

Feature

Claude AI Content Pipeline

The blog runs almost fully automated. Claude generates drafts, a reviewer agent checks SEO and quality, images are created with Imagen 3. I just curate. The pipeline saves me hours every week.

  • • Keywords already researched for you
  • • Multi-stage review process

$ ./monitoring
Feature

Grafana Monitoring

Prometheus metrics, Grafana dashboards, Sidekiq monitoring. I see what's happening on the server in real-time. Not because I have to, but because I can and it's fun.

  • • Puma + Sidekiq metrics

Impact & Learnings

Portfolio, blog, and freelance services in one place. Everything under my control.

Finally I can get all those ideas out of my head without sitting on a text for days.

What I Learned

A portfolio is never finished. But with good architecture, extending it is fun instead of work.

Claude AI content generation works, but only with a solid review process. Blind trust isn't an option.

Self-hosting means more work, but also more control. For me, the right trade-off.
