🏆 Top Rated | 41 mobile apps delivered | 100% Job Success ✅ React Native and Expo, one codebase, live on both stores ✅ AI chat and assistants running inside the app ✅ Marketplace, booking and property apps, iOS and Android I build iOS and Android apps in React Native and Expo, from the first screen to live in both stores. Most of my work is marketplace, booking and property apps for startups and businesses in real estate, healthcare, e-commerce and services, increasingly with AI running inside them. The part these projects usually underestimate is release, so I build to App Store and Play Store rules from day one rather than finding out three weeks after the app is finished. Here's what I can help you with: ✔ AI Features Inside Mobile Apps: in-app AI chat and assistants, smart search, recommendations and automated flows. OpenAI, ChatGPT, Claude or Gemini over the API, with streaming responses on mobile, context handling and token cost kept under control so it doesn't get expensive once real users show up. Works on a new build or an app already in the stores. ✔ Marketplace & Two-Sided Apps: property and real estate apps, franchise and business listing platforms, rentals, classifieds and multi-vendor marketplaces. Listings, search and filters, saved items, in-app messaging between both sides, reviews and ratings, wallets, referrals, Google Maps and location search. Realtors PK and Franchise PK were both built this way and run on iOS and Android. ✔ Booking & Appointment Apps: doctor and clinic booking, telehealth, service scheduling, salon and studio slots. Live availability that won't double book, calendar sync, push reminders, rescheduling and cancellation flows, payment taken at booking, and an admin dashboard for whoever manages it. Doc Reserva is a full appointment system on both platforms. ✔ Startup MVPs: idea to a launched app. React Native with Expo so iOS and Android come out of one codebase instead of paying for two builds, EAS for the release pipeline, onboarding flows that don't lose people on the first screen, and a working app in the stores rather than a prototype you demo off a laptop. ✔ Integrations That Usually Cause Trouble: Stripe and in-app purchases, RevenueCat subscriptions, Firebase auth and Firestore, push notifications on both platforms, real-time chat with Socket IO, video calling, camera and image upload, biometric and Face ID login, deep linking, geolocation and geofencing, offline support, Google Maps and Mapbox, and REST APIs wired to whatever backend you're already running. ✔ Publishing, Fixing & Maintaining: App Store Connect and Google Play Console submission, TestFlight, EAS Build and EAS Submit, and rejected apps sorted out and resubmitted. Crash reporting with Crashlytics, slow screens profiled and fixed, app size reduced, React Native and Expo SDK upgrades, over-the-air updates, and taking over apps a previous developer left half done. I'll tell you honestly what's worth keeping before you pay me to touch it. 💬 What clients say: "Aizaz is an excellent professional, and very reliable as a full-stack dev. I strongly recommend him." Let's have a free consultation to go through what you're building. I'll map out the approach, the stack I'd use and a realistic timeline, and tell you honestly whether I'm the right fit before you commit to anything.
