Designer & Engineer

Kaito Yoneda.

I work across UI/UX and frontend, moving back and forth between design and code.

About

Kaito Yoneda (米田 海翔) — working across UI/UX and frontend engineering.

Weekdays at Funda designing B2B SaaS products. Nights and weekends at ship on Res-Me. I rarely stop at Figma — I usually push designs through to production code.
