What I do and how engagements work.

What I do

I lead end-to-end work in three areas, usually in combination, not in isolation.

Design System engineering

From token primitives to a documented, shipped library, built in code, maintained over time, consumed by humans and AI.

  • Tokens (color, type, spacing, motion) and theming infrastructure
  • Component primitives + composition patterns
  • Documentation site (Fumadocs / Storybook)
  • Adoption strategy and team enablement

Product design

Product work for B2B SaaS, from research to flows, UI, prototype and validation, grounded in the system above.

  • Product discovery and definition
  • Information architecture and flows
  • High-fidelity UI with system-first thinking
  • Accessibility (WCAG 2.2 AA baseline)

AI-native interfaces

Generative UI patterns where AI orchestrates pre-built components, the controlled approach where AI picks artifacts and the system renders.

  • Chat-as-UI patterns (citations, tool calls, plans, artifacts)
  • Machine-readable documentation for design systems
  • Prompt versioning and agentic workflows

How engagements work

  • Discovery sprint (1 to 2 weeks), scope alignment, audit, plan
  • Production (4 to 12 weeks), weekly delivery, shared workspace
  • Handoff, documentation, walkthroughs, async support

Open to project work, fractional roles, and full-time positions.
