Thought through
I build the software myself, from the data model to the UI. AI models, agents, skills and plugins help where they genuinely add value. I stay responsible for the code.
Software for IT operations and security that reduces manual work and runs where you need it. Open source, self-hostable and built without unnecessary overhead.
OpenVizPilot · AI copilot for Tableau
Ask questions right inside the Tableau dashboard, get evidence-backed answers with traceable provenance, run proposed actions with a click. Self-hosted, with your LLM and the permissions Tableau already knows.
Six more applications for work that otherwise piles up: UI changes for coding agents, project keys for Claude Code, automated website updates via SFTP, certificates, company knowledge and club administration. All self-hostable.
Your UI. Your feedback. Agent-ready.
Edit, move and annotate elements directly in your browser. Turn visual feedback into actionable instructions for your coding agent.
The right key for every project.
Manage approved LiteLLM keys on macOS and Windows and assign them to project folders. Claude Code automatically uses the right key in VS Code, IntelliJ and the terminal, with no manual switching.
The website, kept in step with your releases.
Keeps a static website in step with product releases and publishes it: Claude Code updates the content, the app builds, commits, pushes and uploads via SFTP, then checks the live site byte for byte.
Keeps an eye on your certificates
Keep every certificate in one place, catch expiry and revocation early, and check renewed certificates on live systems. Enterprise adds SSO, partner exchange and mail encryption.
Knowledge portal and chat with sources
Find knowledge in documents, email and Confluence without giving up control. With agent mode, technical identities for external integrations and full-platform Helm deployment.
Club management for German allotment gardens
One local place for club administration: plots, tenants, inspections, appraisals, meter readings and invoices. Member data stays with the club.
This is how I build software that holds up in everyday work.
I build the software myself, from the data model to the UI. AI models, agents, skills and plugins help where they genuinely add value. I stay responsible for the code.
The core is open source and stays that way. You can inspect the code, run the software yourself and contribute your own changes.
Your data stays on your servers. There is no mandatory cloud. When you stop using the software, your database and containers go with you.
Questions and bug reports come straight to me. You speak to the person building the software.
What comes up while building and running the products — and what I learn from it.
Processed is not published, permissions act inside the query, no sources means no answer — and what has been added since v0.2.1: agent mode, technical identities, disaster recovery, horizontal scaling and SSO sign-in for MCP.

Four days, ten stages, a playable pixel-art action RPG: what came out of the 250-$ credit I was given, how working with Claude Code actually went, and what it cost in tokens.
