About

I build AI-native products end to end: agents and retrieval, the APIs and data behind them, and interfaces that hold up at millions of users. 10+ years across Sky/Peacock, Diligent, BMW Group, eino.ai and Moment (as VP of Engineering); now Lead Engineer at Fueled. Open source, built in public: onsystem keeps coding agents on your design system, ondocs is open-source Ask AI for your docs, and signoff-ui lets you review what an agent changed and approve what it may do. Lisbon, remote on US-aligned hours.

onsystem - Keep coding agents on your design system

onsystem checks agent-written React against your real components and tokens: palette colors, native elements and APIs your design system lacks, at every edit and pull request, with the fix. MCP server, Claude Code plugin, ESLint plugin and GitHub Action. MIT.
