As part of the Mixed Reality Design team, I lead design efforts for the developer and creator ecosystem, focusing on the open-source MRTK project. I work closely with technical designers and engineers to develop and share essential spatial interaction patterns and UI controls for Mixed Reality.
With a background in engineering and experience publishing apps across various platforms, I bring a deep understanding of both developers and creators. I support the team in executing our design vision by refining visual and interaction designs, creating example scenes that showcase core building blocks, and writing comprehensive design and technical guidelines.

2D UX DESIGN
2011 – 2015
As a UX designer, I worked with engineers, program managers, and user researchers to design the best content consumption experience for Microsoft’s MSN/Bing Apps on various platforms – News, Weather, Sports, Finance (Money), Travel, Health & Fitness, Food & Drink apps for Windows, iOS, Android, and web. In a small design team of 5-10 people, I was responsible for the entire design process – ideation, sketching, prototyping, information architecture, navigation, data visualization, interaction design, visual design, and branding.
As a designer with engineering experience, I established a deep collaboration relationship with the engineering team. I drove hands-on design integration to achieve the pixel-perfect design in the production phase. By several media, Bing/MSN app suites were considered as the best Windows apps that showcase Microsoft’s new Metro design language with rich content and fluid user experience.
Focus Areas
• Visual design
• Interaction design
• Information architecture
• Navigation
• Common UX
• Motion design
• Prototyping
• Design integration
