"Good design is actually a lot harder to notice than poor design, in part because good designs fit our needs so well that the design is invisible."

-Don Norman-

Welcome to my portfolio! Here you’ll find highlights of my work, and I’d love to connect if you have any questions.


A bit about me—I’m Yen, a designer since 2015, currently based in Germany. I’m passionate about technology and its potential to enhance and simplify daily life. My goal is to use design to create meaningful, positive change, making technology both impactful and convenient.


Outside of work, I enjoy catching up with friends, cooking, traveling, and reading. Yoga is my favorite way to stay active and balanced.

Recognized by my Team

“I had the pleasure of working with Dang Yen on our AR inspection app, where her skills in UI and UX research truly stood out. She effectively gathered feedback from users, iterated designs, and collaborated seamlessly with our team to improve the user experience. Her dedication to creating intuitive interfaces and her ability to translate insights into actionable design changes were invaluable to our project’s success. I highly recommend her for any Senior Product Designer role.”

Dr. Thomas H Treutler | Director

“Yen always tries to improve and strive for the best user experience. She questions designs that don’t work because of missing usability and creates multiple designs to find out what is the best way without going into a tunnel vision. Yen’s strength is to find designs that look great, fit well into the defined scope and serve the UX. Her designs and the features we delivered were always so well perceived by our customers, that we didn’t need a lot of adjustments. ”

Stefanie Hörnig | Manager

“It was a great pleasure working together in one design team with Yen. She is a dedicated and passionate specialist who has an outside the box thinking and a very strong eye for the details. During our cooperation Yen was a real gatekeeper of design who kept great care of our design system and overall visual consistency of the product. I'm so happy to have worked together with Yen, as she is a great colleague, team player and simply a wonderful person.”
