## About

```text
At Delivery Hero, I designed and built Cape Fly, an agentic RAG Slack bot using Gemini on Vertex AI. It’s used by about half of the design-system community, and replies went from about one day to under 10 seconds.

I’ve built Cape’s component libraries, design tokens, and CI, including a custom MCP server that grounds Claude’s UI generation in real component and token contracts. I also led frontend delivery of an executive KPI dashboard and built an internal developer portal from scratch.
```
