Seeking a Long-Term App Partner to Design, Build and Launch on iOS and Android

FOUNDING MOBILE PRODUCT ENGINEER Design, Development and App Store Launch Remote | UK time zone | Long-term partnership | Immediate start | Individuals only, no agencies ABOUT ME I'm a solo founder running a fast-growing digital learning platform. I don't come from a technical background, and my tech skills are fairly basic. However, I believed in the idea enough to teach myself how to build and launch a web app on Lovable as an MVP. The response has exceeded my expectations. The platform now has thousands of paying customers, millions of views across social media, and consistent monthly revenue. The concept is proven. The next step is to scale it properly, and I'm looking for the right person to do that with me. THE OPPORTUNITY I'm looking to move the platform from its current web app to fully native apps on the App Store and Google Play, and then grow it significantly from there. This isn't a one-off contract. I'm looking for a long-term technical partner: someone who will design, build and launch the app, then continue to lead its development as the business grows. You would own the technical side of the business, while I focus on content, marketing, customers and growth. Please note this role is for an individual only. No agencies, please. SPEED IS A PRIORITY The market is moving quickly. Competitors are paying attention and starting to copy what we do, so getting to market fast is essential. This project needs to be delivered as quickly as possible, without cutting corners on quality. I'm looking for someone who can move with urgency, make decisions quickly, and ship high-quality work without unnecessary delays. In return, I'll make sure nothing on my side slows you down. You'll get fast feedback, quick sign-offs, and everything you need from me, when you need it. A STRONG STARTING POINT You won't be starting from a blank page. I've already prototyped the look, feel and core features I want for the app, so you'll have a clear foundation to build on. We'll develop the product together. I'll bring the product vision and a deep understanding of what works for my customers. You'll lead on all technical matters, including architecture, tooling, performance, security and scalability, and I'll trust your judgement on those decisions. SCOPE OF THE INITIAL PROJECT • Design: refine the existing prototype into polished, production-ready screens in Figma for iOS and Android, including the app icon and store assets • Development: build the app in React Native with Expo, with a Supabase back end • Core features: - Learning content with audio narration - Swipe-style flashcards and quizzes - Timed mock tests - Interactive video challenges - A TikTok-style short-form video feed - Progress tracking • Payments: in-app subscriptions through Apple and Google, using RevenueCat • Supporting features: push notifications, crash reporting, analytics, and an admin panel for managing content and uploading videos • Launch: beta testing, store submission and approval on both platforms REQUIRED SKILLS • ESSENTIAL: a strong eye for clean, modern UI design, with the ability to turn those designs into polished, fully working apps on the App Store and Google Play • Mobile UI/UX design in Figma • React Native with Expo, including EAS Build, Submit and Update • TypeScript • Supabase (authentication, database, storage and security rules) • In-app purchases and subscriptions, ideally with RevenueCat • Video playback and streaming • Push notifications, crash reporting and analytics • App Store Connect and Google Play Console, including handling review rejections • Git and GitHub ABOUT YOU • You're an individual, not an agency • You can work within UK hours (GMT/BST), with good overlap for calls, feedback and quick decisions • You can design clean, modern interfaces AND build them into high-quality apps ready for both app stores. This is essential. • You have designed AND built at least 2 apps that are live on both stores • You speak clear, fluent English for regular calls and updates • You have a reliable internet connection. If this is a barrier, support can be arranged for the right person. • You work quickly without compromising on quality • You're comfortable owning a product from start to finish • You're happy to lead technical decisions and explain them clearly • You communicate proactively and keep progress visible • You want to be part of a growing business, not just complete a contract • Experience with education, quiz or video-based apps is a strong advantage WHAT I OFFER • A proven business with paying customers from day one • An existing prototype and a clear product direction • A committed, responsive founder who will keep things moving • Competitive pay for the initial build, paid by milestone • A genuine long-term role as the platform grows, with openness to discuss how the partnership is structured HOW TO APPLY Please send: 1.
