Collaboration

Design is a team effort. I translate business strategies into product roadmaps by facilitating collaborative, in-depth discussions with cross-functional teams and working closely with engineers to create exceptional user experiences. Effective communication is essential for productive and fulfilling workplace relationships, and I strive to embody that principle. Here’s what some of the people I’ve worked with have to say about my collaborative style and approach.

“Kellie Sun is the unicorn designer who is not only a fantastic designer who is able to empathize with users and clearly communicate ideas, but she is at home contributing to both business/strategy and technical implementation discussions, ensuring all information is incorporated into her design decisions.”

Benjamin Bueno De Mesquita
Product Manager

“During the year that we worked together, I learned so much from her, from the little things I did not know about Figma, to the game changing concepts she guided me through with user research and product journey. She is also a big design advocate and evangelist. She always strived to elevate our design culture within the company.”

Joanne Schuster-Rocafort
Senior Product Designer

“She truly is a design visionary and has demonstrated an exceptional ability to translate abstract ideas into usable features. Her design leadership has left an indelible mark on our company and has raised our design standards to new heights.”
