AI chat and assistants, in-app purchases, Firebase and Supabase backends, and the App Store and Play Store release at the end. Here's what I can help you with: ✔ AI Feature Integration: OpenAI, Claude and Gemini wired into a live app for chat, assistants, AI search and recommendations, with RAG over your own documents where the answers have to be grounded. ✔ React Native App Development: Expo, bare workflow, Expo Router and the New Architecture, from a first MVP through to a production build, written in TypeScript so the next developer can read it. ✔ App Store and Google Play Release: EAS Build and Submit, Fastlane and TestFlight wired up once, then submission, review responses, rejection fixes and SDK upgrades on apps that stopped building. ✔ In-App Purchases and Subscriptions: RevenueCat, Superwall and Stripe, with paywalls, trials and restore flows tested on both stores. One subscription app converts 65% of trials to paid. ✔ Firebase and Supabase Backends: Firestore, Auth, Cloud Functions, Postgres, row level security, storage and edge functions, with offline sync for apps used on a building site or a plane. ✔ API Integration: REST and GraphQL wired into an existing product, with retries, token refresh and a fallback for every call that can fail. ✔ User Authentication and Profiles: email, phone, Apple, Google and social sign-in, profile creation, roles and the account deletion flow Apple now demands before review. ✔ Tablet and iPad Builds: the same codebase laid out properly for iPad and Android tablets, which eleven live briefs asked for this month and almost nobody advertises. ✔ Real-Time Features: chat, live feeds, presence, WebSockets, push notifications and location tracking that survives the phone going to sleep. ✔ Existing App Rescue: taking over an app whose developer has gone, or a prototype built in Cursor, Lovable or Manus, and making it production ready. ✔ Social, Community and Events Apps: chat and messaging, group and event rooms, profiles, live location and AI search. The best-paid cluster I work in, and the one I ship most often. ✔ Health, Beauty and Fitness Apps: appointment and salon booking, telehealth, patient and driver apps, habit and streak tracking, on-demand training video, with scheduling and reminders built in. ✔ Commerce, Travel and Logistics Apps: in-app ordering, price tracking, flight and tour booking, hospitality management, driver dispatch, ride booking and parcel or ride tracking on a live map. ✔ Fintech, Education, Construction and Faith Apps: banking and savings, vouchers and QR verification, e-learning and quizzes, field estimating and site capture, devotional and nonprofit community apps. What clients say: "Excellent developer. Fast, skilled, communicative, and reliable. Delivered high-quality work and made the whole process smooth. Highly recommended." Let's have a free consultation about your app. I'll tell you which features belong in version one, what Apple's review is likely to flag, and how long the build actually takes, before you commit to anything.
