Research-led UX design for product teams

UX design & prototyping services

Turn research insights and product requirements into user flows, wireframes and interactive Figma prototypes your team can test before development. When your product needs high-fidelity UI, I bring in trusted UI designers from my network.

Scope

Flows to prototypes, UI with partners

Tools

Figma, FigJam, Miro

Approach

Research-led, tested with users

When do you need UX design and prototyping?

A good fit if

Requirements need to become flows, wireframes and a prototype your team can test.

You want to explore ideas before development starts.

An A/B test needs a well-reasoned variant, not a guess.

You need research-led UX and high-fidelity UI with one point of contact.

Not the right fit if

You only need a visual refresh and have no open UX questions.

You need a large design team for ongoing production work.

You need the product built. Development stays with your team.

There is nothing to base concepts on yet. Start with user research.

Not sure what the concept should solve? Discovery research shows what people actually need.

What I create

UX design services from insight to testable prototype

Grounded in research and behavioral psychology, built in Figma. AI tools speed up iterations on mid-fidelity prototypes. High-fidelity UI comes from trusted design partners.

UX and UI design

From UX concepts to complete UI design

I lead research, UX structure and prototyping myself. When your product needs high-fidelity UI, I bring in independent UI designers from my network and coordinate the work where agreed. You can start with a focused concept and extend the scope later.

UX research & concepts

Led by me: flows, wireframes and prototypes based on evidence.

UI & visual design

With trusted design partners: high-fidelity screens, components and responsive layouts.

Testing & handoff

As agreed in the scope: usability tests, iterations and files for your developers.

How it works

STEP 1

Start from evidence

We collect what is known: research findings, data, requirements and constraints.

STEP 2

Map flows and structure

I define the information architecture and key user flows before designing screens.

STEP 3

Wireframe and prototype

I create wireframes and interactive prototypes in Figma, iterating fast with your team.

STEP 4

Test with users

We test the concept or prototype with real users or define it as a variant for an A/B test.

STEP 5

Extend into UI and hand over

For high-fidelity UI, trusted design partners join. Your team gets editable Figma files and the reasoning behind each decision.

What you’ll receive

Concepts your team can discuss, test and build on, each one linked to the insight or hypothesis behind it.

Tested concepts

Tested with real users when testing is part of the scope.

Screens, components and handoff files from trusted design partners, when you need them.

Ready to make your ideas testable?

What it can and cannot do

A prototype makes ideas testable. It doesn’t prove they work.

Concepts are hypotheses until people use them. That’s why I design them to be tested, with users or in an A/B test.

A shared picture

Everyone sees the same solution before it is built.

Faster decisions

Ideas can be compared, discussed and tested early.

Testable variants

Clear alternatives for usability tests and A/B tests.

Ways to work together

From a single concept to complete UX and UI design, scoped to your question and timeline.
