I build accessible, sovereign UI for the public sector — and the tooling that keeps big open-source repos maintainable.
- ♿ Accessibility-first — BITV 2.0 / WCAG as a default, not an afterthought
- 🇪🇺 Digital sovereignty — European-native, EUPL-licensed open source
- 🧩 Web Components over lock-in — framework-agnostic by design (built on Stencil)
- 🔐 Secure supply chains — SBOM, SLSA, DevSecOps as standard practice
- 🤖 Automating the boring parts — agentic routines for issue triage, PRs & releases
