About this service

Summary

I help teams bring mobile app ideas to life—from first sketch to clickable prototype. My process blends strategy, design, and interaction details, creating experiences that are easy to test, refine, and hand off to development. Whether you need a new product built or an existing one reimagined, I focus on clarity, speed, and user-friendly results.

FAQs

What tools do you work in?
Figma is my primary design tool. I can also provide exports for Sketch, XD, or dev-ready assets as needed.
Do you handle development?
My focus is design, but I collaborate closely with developers and can connect you with trusted partners if needed.
Can you work within my design system?
Absolutely — I can adapt to existing systems or help define a new one.

We've worked with Casey on numerous projects. Casey has an excellent eye for visual design and a pragmatic approach to user experience. He can create designs that are both beautiful and easy to use. He is comfortable in a wide array of design disciplines and can think through complex flows as well as small details that set projects apart. Cannot recommend Casey enough.
