Things I build in my own time to explore ideas I later bring into client work.
New experiments land there first.
A bilingual, headless portfolio platform built on Next.js and Strapi 5.
The open source monorepo that powers this very website: a Next.js frontend rendering CMS-driven page sections, a Strapi 5 backend with EN/DE localisation, and a zero-dependency media pipeline that stores uploads directly in SQLite.
A coordinated team of specialised AI coding agents for real-world repositories.
A curated set of agent definitions, skills and coordination protocols for opencode: an orchestrator that plans and delegates, specialists for backend, frontend, performance and documentation, and reviewers that approve or block with evidence.
Policy and instruction templates that keep AI coding assistants on track.
A starter kit for teams adopting AI coding assistants: versioned instruction files, policy templates, a linter that checks them for contradictions and a CI step that flags risky AI-generated changes for human review.
