Your idea as something people can open and try: a landing page or two or three core screens, built in code on a live URL, with real states and mock data. It opens on any phone from a link, no accounts and no app store between your tester and the idea.

The screens designed and built the same week: states working, empty, loading, and error included; mock data standing in for the backend, including the slow and empty moments. Dev-ready Figma files come with it, carrying the tokens and components with every state of every screen, so production later starts from a system rather than screenshots. One revision round after the walkthrough.

There is no production code behind the screens, and that's the point: the build exists to be tested, then thrown away without regret. A full user journey, several user roles, or two account types is a bigger animal; that scope gets a quote after a short call, typically $5,000–$9,000. Anything that has to survive contact with production belongs to my design and front-end build service.

Half an hour on a call, with the idea in whatever form it lives: a deck, a voice note, a napkin sketch. I design the screens and build them the same week, and you watch the URL fill in as it happens. We close with a walkthrough.
