The UX expertise behind every project

The core parts of every product we design, and what each one means for you.
UX design

UX design shapes how a product works and feels. We study your users and map their goals, so every screen helps people finish tasks with less effort.

UI design

UI design is the visual layer of your product: layouts, colors, type, and buttons. We design polished, on-brand screens in Figma that make every action clear and easy to find.

Usability

Usability is how easily people can complete tasks without errors or confusion. We design clear labels, simple navigation, and obvious next steps, so users spend less time guessing.

User flow

A user flow is the path someone takes to complete a task, like signing up or checking out. We map your core flows first, so every screen has a clear purpose and every step leads somewhere useful.

User persona

A user persona is a fictional profile built around real user goals, needs, and frustrations. We use personas to keep every design decision focused on the people who will actually use your product.

Information architecture

Information architecture is how content and features are organized and labeled. We structure menus, pages, and screens so users can find what they need quickly, without searching or guessing.

Wireframe

A wireframe is a simple, low-detail layout that shows structure and content placement. We use wireframes to agree on layout and flow with you early, before any colors or visuals are added.

Prototype

A prototype is a clickable model that shows how your product will work. We build interactive prototypes you can test with users, show to investors, and refine before developers write any code.

Design system

A design system is a library of reusable components, styles, and rules. We build one for your product so every screen stays consistent, and your developers can build faster with less guesswork.

Responsive design

Responsive design makes a layout adapt to any screen size, from phones to desktops. We design every key screen for each device, so your product feels natural and looks right wherever it's used.

Accessibility

Accessibility means designing so people with disabilities can use your product. We design with WCAG guidelines in mind: readable text, strong contrast, and comfortable tap sizes.

Usability testing

Usability testing means watching real people try to complete tasks in your design. We prepare prototypes ready for testing, so you can spot problems and fix them before launch, not after.

Questions before you get started?

How much does UI/UX design cost?

Every service has a fixed starting price: MVP design from $1,900, website design from $1,700, mobile app design from $2,400, and dashboard design from $3,700. You get a fixed quote before any work starts.

Do you build what you design?

For websites, yes. We can build them in Framer, or as a custom build for sites that need more complex features. For apps and dashboards, we hand off dev-ready, AI-ready files and answer your developers’ questions. If you don’t have a developer, we can connect you with one we trust.

Can you redesign my existing product?

Yes. We review what you have, keep what works, and redesign the structure, flows, and visual style.

Do you sign an NDA?

Yes. We sign one before you share any project details.

How do you work with clients in other time zones?

We work remotely with clients in the USA and Europe. You get weekly updates, and we reply to every message within 8 hours.

What do “AI-ready” files mean?

Your Figma files are organized with clear names, components, and specs, so developers and AI coding tools can turn them into code more accurately.
