Design System
| Quin
Quin’s growing product suite was becoming hard to manage. Components drifted, quality slipped, and teams lost time reinventing solutions. I helped design and implement a system that aligned design and development, improved quality and accessibility, and gave the company a scalable foundation to build innovative healthcare products with confidence.

Smart Triage
UI/UX Design
| Quin
Specialists were overloaded with routine cases while patients with complex symptoms waited months for care. With Smart Triage, we set out to fix how referrals moved through the system. The goal was to design an AI-supported workflow that helped doctors focus on what mattered most, combining automation with human expertise. I turned research into interactive prototypes, shaping an experience that improved speed, clarity, and trust across the care process.

Clear Accounting
Design System
| Yuki
Yuki’s accounting platform was powerful but fragmented, with each team building features their own way. It worked, but not smoothly. We built a shared design system that brought structure, clarity, and consistency to the entire platform. I led the visual direction and helped design the system from the ground up, creating modular components and a bold, approachable interface that made accounting easier for both users and teams.

Mobile Accounting
UI Design
| Yuki
Most small business owners aren’t at their desks all day, but their accounting tools often assume they are. The Yuki Assistant project aimed to change that by bringing the full power of Yuki’s accounting platform to mobile in a fast, clear, and reliable way. I helped redesign the app to make financial data easy to read, navigate, and act on, using the new design system to create a scalable, modern experience that helped users stay in control wherever they worked.

Patient Engagement
UI/UX Design
| Trialbee
Clinical trials depend on patient commitment, yet long timelines and complex procedures often cause dropouts. At Trialbee, I worked on a mobile app designed to keep patients informed, motivated, and connected throughout the trial journey, from recruitment to treatment.
