I designed for the internal platform Costco's developers build their tools on, and worked across a number of projects.
Design system tokens. Added variables and code syntax to 2,000+ components of Costco's internal design system in 3 days, against a 3-week schedule, with Figma's Canvas Agent — then checked every one against the code tokens with the system's developer. Walkthrough →
Agentic AI landing page. Designed the landing page for Costco's first agentic AI, and handed the hero off as a working three.js component. It shipped to production in one sprint. Walkthrough →
Design system components. Designed the breadcrumb, error page, sign-on and sign-out flow, and nav bar menus for the design system.
AI skills and workshops. Wrote 10+ Canvas Agent skills — contrast audits, design-debt checks, alt text — and taught them in workshops. 5+ are now shared with designers across Costco.
Some aspects of this work aren't public — the walkthroughs above are password-protected. If you want to dig into the details, reach out at daphne.cheng.design@gmail.com and I'm happy to talk through them!
