GAP INC
Customer Profile
Gap Inc's Profile pages are used by customers to set up and manage their personal information across their brands’ eCommerce sites. These pages encompass the entire lifecycle of a user account, including registration, authentication, saved settings, and order details. In 2019, I redesigned all Profile pages into a cohesive, easy-to-use experience for customers.

TRNIO
3D Scanning
TRNIO is an iOS app offering mobile 3D scanning and sharing. TRNIO was concerned that new users were having difficulty using the app. Informed by extensive usability testing, we redesigned the app to leverage the use of augmented reality, featuring a graphic overlay in the camera view to guide the user through the scanning process.

About
Charlene
I'm Charlene, a designer
based in the Bay Area.
With more than a decade of experience in product and service design, I bring a thoughtful, user-centric approach to UX design.

My work across multiple sectors — including eCommerce, tech, healthcare, and consulting — has led me to a simple truth: design is about problem-solving. How can we create a product that is not only functional, but also highly usable and ✨ aesthetic ✨? By focusing on the user while maintaining the business context, I aim to transform complex challenges into intuitive experiences that resonate and perform.

Tell me about your next project. I'd love to hear from you.
