Copilot and agents in Azure Portal search

Users often come to search without knowing exactly what they need. I defined the journey from that vague starting point to Copilot and agents taking action on their behalf.

  • 50k+Drove increase in incremental Copilot users per month
  • 93.2%Search success held, with abandonment effectively unchanged
  • Mapped how a search query becomes an AI-assisted task, and where people stay in control
  • Used vibe coding tools to prototype Copilot and agent flows quickly, so the team could react to working experiences instead of static specs
  • Used those prototypes to align design, PM, research, and engineering on one direction

Led 0-to-1 design for iOS and Android and owned the UX roadmap with engineering for 5 years. The team had no working model between design, PM, and engineering when I joined, so I built one alongside the product.

  • 35K → ~200Kmonthly active users at peak
  • 30+features shipped
  • Grade BFirst product in the C+AI org to reach MAS Grade B accessibility
  • Owned the UX roadmap in close partnership with engineering
  • Set up the cross-discipline reviews and rituals the team didn't have before
  • Made accessibility part of the design from the start

Azure Portal Global Search

Global Search is how people find resources, services, and docs across the portal. I led its move to React and Fluent 2 with accessibility at the center, then used research to set where search goes next.

  • 50M+monthly search interactions
  • Made the case for React and Fluent 2 and partnered with engineering to land it
  • Led accessibility and UI improvements across the search experience
  • Ran usability studies with research to shape a roadmap for semantic search, personalization, intent recognition, and AI discovery

Iconography and logos

From game HUDs to Microsoft product marks, I've designed icons and logos and built the systems that keep them consistent.

  • 1000+icons hosted on IconCloud across Azure, Fluent, and Windows
  • 400+icons shipped for the original Destiny 2 launch
  • Built the Azure icon system from scratch: visual design guidelines, a request intake process, a GitHub repo, and naming conventions. Collaborated to create IconCloud.
  • At Bungie, crafted a high volume of icons, improved clarity across complex HUD and game systems on PlayStation, Xbox, and PC
  • Additional logo work for the Azure "A" mark, Microsoft Entra, Microsoft Authenticator, and Cloud Experiences Studio

About

I got my start in visual design and marketing, spent a few years bouncing around freelancing opportunities, and eventually landed at Microsoft, where I currently design experiences for the Azure Portal.

Over the course of my career, I've gotten really good at creating process where there was once none, or re-envisioning what products could be for customers.

I like to prototype early so people can react to something real, I treat accessibility as part of the design rather than a last check, and I enjoy mentoring early-in-career designers.
