// Testimonials

"I worked with David for over a year and was constantly impressed by his work ethic, ability to navigate difficult conversations, and overall talent for creating clean, user-centric designs. I can personally attest to his ability to use Figma for implementing (design) standards, as we worked primarily from Figma for all of our user stories. I would be happy to speak to his skillset in more detail if requested."

- Juliana Garabedian
User Assistance Developer at SAP

"David was such a pleasure to work with! At the time, we were mostly using Adobe XD. Now, we mostly use Figma (a web-based collaboration tool) for the UI & UX Design phases of our projects thanks to David’s influence. Aside from sharing great ideas, tools, insights, and resources, I would highly recommend David for his analytical approach to tasks and his solid grasp of UX design."

- J.D. Talamayan
Web Developer at smartboost

"David is an excellent researcher who has a knack for organizing his data and findings into actionable steps and recommendations. If I were to describe David's work ethic in two words they would be 'effective' and 'efficient'. David is a great and dependable role player."

- Eric Rudeen
Project Manager at smartboost

"I was consistently impressed with David’s dedication to
design and user research.
In addition to his great work ethics, he’s also a great listener. He took the time to learn about the Kano Model and conducted surveys, so his team could be informed about what direction their ideas could go."

- Karen Yeung
Senior UX Designer at Dexcom

"David has gifted UX/UI skills. He has demonstrated his ability to think logically and systematically. He has been working with creativity using both data and 'think outside the box' skills. Fantastic work ethic."
