Turn your product idea into a working interactive prototype you can test, demonstrate, and develop further.
I help founders and teams define the key user journey, design the interface, and build a working browser prototype. This can be a new product, a feature, or an existing workflow that needs a clearer direction.
What you get • A focused scope and core user flow • Designed screens and interactions for the agreed journey • A working prototype with relevant interface states and responsive behaviour • A shareable demo and source code handover • Clear notes on what is simulated and what is needed for the next build
How we work We start with your idea, audience, and the decision the prototype needs to support. I shape the flow, build the agreed experience, and refine it through feedback. We agree upfront which parts use live data and which are simulated.
Pricing and timing depend on the scope and are agreed after reviewing your brief.
