Sam J.
App Designer & AI Engineer | AI Prototypes to Finished Apps
I turned a client's AI built prototype into a live app in six weeks. It's now grown to over 550 screens, with real users. That's what I do. You've built something with Lovable, Bolt, Claude or ChatGPT, it proved the idea, and then it got stuck. It breaks when you change things, it doesn't look like a real product, and it isn't ready for paying customers. I turn it into one. What I do: • Design and build the finished app, ready for the web now and the App Store and Google Play later • Give it a proper brand and design system, so it looks and feels premium • Add the AI features and automations that make it useful • Build the back end it needs: accounts, data and payments Recent work: • Money From The Inside Out: a personal finance app taken from the client's own AI prototype to launch in six weeks, now 185 pages and over 550 screens, with a full brand and design system • A live Champions League sweepstake app for over 100 players, saving the organiser around 60 hours across the season You work with one person from start to finish. I design every screen and build it myself, using AI, which is how one person covers design, build and AI to a finished standard. I'm based in Manchester, UK, with native English, and my working day covers the UK and European day and the US morning. Send me a link to what you've built, and I'll record you a short video of what I'd do first.
