How I work

End-to-end process

From first alignment to shipped product, I focus on research, design, and the engineering bridge for a seamless handoff between cross-functional teams.

Research

  • User interviewsStructured conversations to uncover mental models and unmet needs
  • User surveysQuantitative signal at scale to validate or challenge qualitative findings
  • Competitive analysisMapping the landscape to identify gaps and positioning opportunities
  • Heuristic evaluationExpert audit against usability principles before any testing begins
  • Usability testingObserved task sessions that surface friction before it ships

Design

  • Wireframing & prototypingLow-to-high fidelity flows iterated fast, tested early
  • Visual designPurposeful hierarchy, type, color, and motion that earns trust
  • Design systemReusable component libraries that scale across surfaces and teams
  • AccessibilityWCAG-conformant from the start — not a post-launch checklist

Build & handoff

  • Design token architectureSemantic token pipelines that sync Figma to code with zero drift
  • MCP server setupDesign token pipelines wired directly into AI-assisted dev environments
  • Figma Dev Mode specsAnnotated, inspection-ready files engineers can build from immediately
  • Component annotationState, interaction, and edge-case documentation baked into the handoff
  • AI-assisted dev workflowClaude Code and Cursor prompt setup so the handoff keeps moving after Figma
