Your app idea deserves a developer who has actually shipped real products - not someone who just knows the theory. I build high-performance iOS and Android apps using React Native that real users love using. Clean code, smooth performance, and AI capabilities built in from day one - not bolted on as an afterthought. In 8+ years of mobile development, I've built real-time systems, white-label platforms, multi-tenancy architectures, and production apps published on both Google Play and the App Store. I don't just write code - I scope properly, communicate clearly, and deliver what was actually agreed. AI-Powered Mobile Development - The best apps in 2026 have intelligence built in. I integrate: - ChatGPT & Claude AI into mobile interfaces - AI-powered search and recommendations - Voice interfaces and smart automation - OpenAI API and LLM integrations into React Native apps --- Mobile Expertise --- - React Native & TypeScript - production grade - Expo & React Native CLI - iOS & Android - published on both stores - MVVM/MVP/MVC architectural patterns - Push notifications - FCM & OneSignal - In-app purchases & payment integrations - Deep linking for seamless user flows - AppCenter & FastLane for CI/CD - Jest, RNTL & Detox for testing --- Full Stack Support --- Frontend: React, Vue, JavaScript, TypeScript, Vite Backend: Node.js, PHP, Laravel, Python Databases: MySQL, Firebase Cloud: AWS, DigitalOcean --- How I work: --- I care about your product as much as you do. Before writing a single line of code I make sure the scope is crystal clear - specifications, wireframes, timeline, and budget. No surprises. No scope creep. Just a working app delivered the way we agreed. 100% client satisfaction. Every project. Not because I promise it - because I actually deliver it. Ready to build something great?
