// how I work with AI · ECA International

From Jira ticket to shipped UI, with AI in every step.

I built an AI-friendly UI kit with shadcn and design tokens, documented in Storybook, then published it as a design system in Claude Design. Now every ticket the team picks up starts the same way:

  1. 01Jira ticket

    Read through Atlassian MCP

  2. 02Design prompt

    Claude Code drafts it from the ticket

  3. 03Claude Design

    Builds UI from our design system

  4. 04Attached to ticket

    The design becomes the spec

  5. 05Delivery

    Claude Code implements, I review

Example Claude Code session
$ claude "pick up ECA-1423"
→ reading ticket via atlassian-mcp… ✓
→ generating design prompt… ✓
→ design attached · branch created · PR opened for review

Things I build to learn.

Quick agentic-engineering builds, done in my own time to try out what the latest models can do. Not polished products, just the playground.
