Mobile App Developer || MVP to App Store || React Native, Flutter, iOS

Funded startups hire me to take a mobile app from plan to a revenue-generating launch on the App Store and Google Play. The last app I led as mobile developer now does $10.8M ARR with 80,000+ paying subscribers and a 5.0 rating on both stores. In 7+ years on iOS and Android, apps I've built have generated $15M+ in revenue for my clients, serve 110,000+ paying users, and hold 5.0 ratings across 10,000+ App Store and Google Play reviews. You might be shipping your MVP, rebuilding a V2 your first version outgrew, or holding an AI-built prototype that's stuck before launch. Anyway, I take it the rest of the way: architecture, build, store approval, and the payment, compliance, and edge-case work that decides whether an app survives real users. 𝗣𝗿𝗼𝗼𝗳 (𝗮𝗹𝗹 𝘃𝗲𝗿𝗶𝗳𝗶𝗮𝗯𝗹𝗲 𝗼𝗻𝗹𝗶𝗻𝗲) - PawSquad: pet care subscription app. Lead mobile developer. 80,000+ paying users, 3,300+ reviews, 5.0 on both App Store and Google Play. $10.8M ARR. - Jasomi: fintech app, built end to end. 10,000+ active users. - ConnectingKnox: local business discovery app. 193 paying businesses onboarded in month one. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 1. Blueprint. Every feature, cost, risk, and timeline on paper before any code. You know exactly what you're paying for. 2. Weekly builds. You see and test a working app every week. No black box, no "it's almost done." 3. Launch. I handle App Store review, Google Play, servers, and monitoring, so the tech side runs without you. Along the way I catch the things first builds usually miss: bad UX, subscription edge cases (failed renewals, refunds, family sharing), and compliance gaps, before they become expensive. 𝗦𝘁𝗮𝗰𝗸 * React Native, Expo, and Flutter for one codebase on both platforms; * Swift and Kotlin when native is the right call. * Node.js, Supabase, and Firebase backends. * In-app purchases and subscriptions with RevenueCat and Stripe. * Push notifications, live chat, maps and geofencing, and AI features with the Claude and OpenAI APIs. 𝗠𝗲𝘀𝘀𝗮𝗴𝗲 𝗺𝗲 𝘄𝗶𝘁𝗵 where you are now: idea, designs, AI prototype, or a live app. You'll get an honest answer on whether I'm the right fit and what to build first.
