Case studies

F.A.Q.

What's the difference between UI design and UX design?
UX design is about how the product works. Flows, information architecture, user research. UI design is about how it looks and feels. Visual design, components, interactions. Both matter. For many B2B SaaS products, a polished UI paired with solid UX is the fix.
Do you design the user flows, or just the interface?
We focus on UI design. Visual language, components, and interactions. If your flows need rethinking, we flag it. That's usually a separate engagement covered by our Product Redesign use case.
How do you hand off designs to developers?
We deliver Figma files with organized components, detailed specs, and design tokens. We also provide implementation guides. Our specs are dense enough that developers don't need to ask. We're around for clarifications.
Can you work from an existing design system or brand?
Yes. We audit your current system, find gaps, and extend it with new components. Or we refresh it entirely if needed.
How do you handle responsive design?
All components are designed for mobile, tablet, and desktop. We spec breakpoints, responsive behavior, and touch targets. Everything is documented.
What if we want to iterate after launch?
We hand you a living design system in Figma. Your team can iterate. We're available for design reviews or advisory sessions when needed.
Can we keep parts of the old design that work?
Absolutely. We audit what works and what doesn't, then evolve from there. We modernize the visual layer where the flow already works.
Can I run a UI design project through Magic Team?
Yes! Magic Team is a managed team of AI agents and senior humans that ships real code. Connect your repo and get features, MVPs, or bug fixes delivered as PRs, reviewed by Donux senior designers and developers.
