Mostly React Native — it's what I know well and what I actually enjoy working with. I've shipped 42+ products across a lot of different industries: marketplaces, healthcare, fintech, booking platforms, ecommerce, B2B tools. Some of them are still running and growing. I work as a Mobile App Developer, React Native Developer, and AI Developer — and these days those three things often overlap on the same project. The AI Developer side started naturally. Clients started asking for smarter apps — chat features, recommendations, content generation, search that actually works. I learned the tools, integrated the APIs (OpenAI, Claude, LangChain), and also started building full products using AI constructors and platforms where that made more sense than writing everything from scratch. Now it's a real part of what I do, not an add-on. Click Hire or Invite React Native Developer. 📱 TYPES OF MOBILE APPLICATIONS I DEVELOP • Taxi & Transportation Apps • Booking platforms • Fitness & Health Apps • AI-based mobile systems • Security-focused iOS and Android solutions • Social media and streaming platforms — social media app, live streaming app, video streaming ecosystems • Fintech & Payments Apps • E-commerce ecosystems connected with WordPress and Shopify • Business & SaaS applications • Wearables & IoT systems — WatchOS, Apple Watch, WatchKit, smart watch integrations • Delivery and Dating Apps 🫵 WHAT YOU GET ✔️ Mobile App Development for iOS and Android — cross-platform React Native builds that actually perform, not just pass review. ✔️ React Native Developer work done properly — solid architecture, clean navigation, auth, payments, push notifications, Firebase, API integration, App Store and Google Play release. ✔️ AI Developer integration — adding AI features to existing apps, or building AI-first mobile products from scratch using AI tools, constructors, and APIs. ✔️ Mobile App Design — I work in Figma, think about flows, and care about UX. Not a designer, but I know when something feels wrong and I'll say so. ✔️ Honest communication — I'll tell you what's realistic, flag problems early, and keep the project moving without needing to be chased. 🔥 WHAT I'VE ACTUALLY BUILT ✔️ 42+ apps delivered as a Mobile App Developer — from quick MVPs to multi-year product partnerships. ✔️ React Native Developer across healthcare, fintech, logistics, wellness, ecommerce, social, and B2B — most categories covered at this point. ✔️ AI Developer projects: AI integrations, AI-powered Mobile App features, and full AI app builds using modern platforms and tools. ✔️ Products that kept users: better retention, fewer drop-offs, smoother flows — that's what matters after launch. 🚚 WHERE I HELP ✔️ New Mobile App Development — MVP to production as a React Native Developer. ✔️ Existing apps — audit, rebuild, or improve what's already there. ✔️ AI Developer work — integrate AI into your app, add smart features, or build something AI-first from the ground up. ✔️ Anything cross-platform — one React Native codebase, iOS and Android, done right. 🏆 WHAT I'VE WORKED ON ✔️ Marketplace apps — listings, search, chats, bookings, payments, reviews, maps, admin panels. ✔️ Healthcare and wellness — onboarding, profiles, appointment flows, reminders, HIPAA-aware builds. ✔️ AI-powered products — AI Mobile App Development with real features: chat, recommendations, smart search, content generation. ✔️ Ecommerce and subscriptions — In-App Purchases, product catalogs, checkout flows, retention mechanics. ✔️ Business tools — role-based dashboards, approvals, reports, notification systems. ⚒️ HOW I WORK ✔️ React Native is my primary tool as a Mobile App Developer. I know it well, I use it daily, and I don't oversell what it can or can't do. ✔️ As an AI Developer I pick the right approach for the project — sometimes that's an API integration, sometimes it's an AI constructor, sometimes it's a lightweight custom build. ✔️ Firebase, Node.js, REST APIs, User Authentication, In-App Purchases — the backend side is covered. ✔️ I'm involved from discovery to release. I'll ask the questions that matter early so we don't redesign things at the end. ✔️ After launch I'm available — bugs, improvements, new features, whatever comes next. 📩 READY TO START ASAP
