AI-First Approach

Where I apply AI in the UX process

• 01Discovery & UX Research

  AI-assisted interview synthesis, qualitative data analysis, insight clustering, data-driven personas and accelerated competitive benchmarking.

• 02Ideation & Prototyping

  AI-assisted, code-based prototyping with Claude Code: functional prototypes in hours instead of weeks, including micro-interactions and realistic data states.

• 03Design Systems

  Automated component audits, design token sync between code and Figma via MCP (Model Context Protocol), living documentation and AI-assisted governance.

• 04Design-to-Code & Handoff

  Automated developer specs and handoff documentation directly in Figma, reducing rework between design and engineering.

• 05Usability Testing

  AI agents that run and analyze usability tests on prototypes, scaling the frequency and reach of evaluative research.

• 06Designing AI-powered products

  Experiences for multi-agent workflows, intelligent notifications and human-in-the-loop interfaces that ensure transparency, trust and user control.
