From people I worked with
Simon Lin
Principal Product Designer @Canva
Ryan is my team member at AAPD, where we teach Figma and UI design. He began as a teaching assistant and quickly advanced to an instructor role, demonstrating strong learning ability, attention to detail, and clear communication. Now, he independently leads projects and works seamlessly with stakeholders, fostering a positive and efficient team dynamic. He’s a reliable and valued collaborator.
Kazuya
Design Manager @PayPay
Ryan was a key team member during my time at PayPay, where he consistently delivered high-quality designs across multiple projects. As a team member, I saw how well he prioritized tasks, communicated with stakeholders, and ensured smooth progress.
He also contributed to Design Ops by improving QA processes and accessibility. His professionalism and proactive approach greatly enhanced our team’s effectiveness and design quality.
Keith Oh
Head of Product Design @Carousell
Ryan was a valued team member who independently led several challenging projects with unclear requirements. He brought clarity through thorough research and tackled problems with patience and a methodical approach. His strong communication skills and collaboration with engineers ensured smooth progress and a positive team dynamic. Yu’s professionalism and reliability made him a trusted contributor.
Belissa
Senior Product Designer @Carousell
Ryan was a former colleague at Carousell, and I was always impressed by his ability to balance user needs with business goals to deliver practical, thoughtful designs. He encouraged collaboration through pair design sessions and brought a positive, solution-focused mindset to the team. His drive for growth, openness to feedback, and creative energy made him an invaluable teammate.
Tom Lee
QA Engineer Manager @PayPay
Ryan is a product designer I worked with at PayPay on several QA projects. He showed great professionalism and attention to detail—from pixel checks to process improvements. When design and development misaligned, he calmly found practical solutions with the team. His suggestions for bug fixes and optimizations boosted both product quality and team efficiency. A reliable teammate, Yu consistently raises the standard of any design outcome.
