Design System Expert & Product Builder — AI Prototyping, design system audit, team transformation
I design, prototype, and ship with AI
I am at the intersection of design, code, and AI.
I design, prototype, and ship with AI
Specifically:I design robust interfaces and products, create products in days with Claude Code and Cursor, and support design teams in adopting these new workflows and optimizing their delivery.
What I do:
◈ Design System Audit & Architecture
I structure, audit, and deploy multi-brand and multi-product design systems — from token strategy to Figma library, including governance and documentation. Result: faster teams, guaranteed UI consistency, a system that scales.
⬡ Product Builders & MVP Startup
You have an idea, a vision, a need to validate quickly. I use Claude Code, Cursor, and Figma Make to transform your spec into a functional prototype or a shippable MVP in days — not weeks. Ideal for startups that want to test before investing in a full tech team.
→ Design Transformation → AI OPS & Workflow
I support design teams in adopting AI workflows: new processes, tools, skill development. The goal: autonomous designers who deliver to production.
