Hey! I'm Mykyta a mobile app developer, react native developer, and full stack developer with 10+ years of experience and 32 successfully released apps. My specialty is end-to-end mobile app development and creating high-performance cross-platform applications for wellness companies, startup projects, and SaaS businesses that actually move the needle. One of my apps earned App of the Day on the App Store. Another helped a startup raise $750k in seed funding. I've scaled products to 100K+ active users and consistently delivered 30%+ growth in user retention. That's not a pitch - that's a track record. 🏄 Why I'm the React Native Expert You're Looking For As a mobile developer, I build apps that feel truly native, not like a cross-platform compromise. Whether you're comparing React Native vs Flutter, need a hybrid approach, or want a flutter developer perspective to make the right framework choice, I help you pick the stack that fits your goals, timeline, and budget. I've shipped apps across iOS and Android using react native, Expo, TypeScript, and JavaScript, handling everything from architecture to App Store deployment. 💻 Full Stack Developer & Web Developer End-to-End Ownership As a full stack developer, I don't just hand off a mobile app and disappear. I own the entire product lifecycle, from web app development to mobile deployment: - Mobile: React Native, Expo, TypeScript, JavaScript, React Navigation, Redux/Flux, GraphQL, Axios, Reanimated, Lottie, Animated, i18Next - Backend & Cloud: Node.js, Nest.js, AWS, Firebase, Supabase, PostgreSQL, MongoDB - APIs, Analytics & Media: Stripe, PayPal, Segment, Appsflyer, DataDog, Sentry, WebRTC, Chart, Image Crop, Video, Push notifications - Auth, Security & Core: Firebase Auth, Auth0, Supabase, KYC/Onfido, React Native Gesture Handler, Device Info, Google Services - DevOps: CI/CD pipelines, Docker, AWS S3, CodePush, Appcenter As a react developer and nextjs developer as well, I complement every mobile product with robust React / Next.js frontends and Node.js-powered backends, so you get one partner for the full stack, not an agency or five freelancers you have to coordinate. 🤖 AI-Powered App Development AI is no longer optional. I build intelligent mobile features that feel natural - LLM integrations, smart recommendations, predictive UX, and personalization layers that make your product stand out. Whether you're a startup or scaling a SaaS product, having an expert in AI-native mobile development on your side is a real advantage. 🚀 MVP & Product Launch - My Specialty I've built MVPs from zero to App Store as an android developer and iOS expert more times than I can count. My process: - Clear milestones and rapid iterations for faster time to market - Secure authentication and scalable user management - UX/UI that converts and retains, I've won Dribbble Awards for this - Post-launch support so your product keeps evolving Clients come to me as a trusted full stack developer partner - not just a coder-for-hire. I've helped businesses double their GPM and achieve at least 42% ROI on their mobile investment. ⚙️ Who I Work With I'm a great fit if you're building: - A React Native cross-platform app for iOS & Android - A SaaS mobile product with a Node.js or Firebase backend - An AI-powered mobile experience -A wellness or health app (deep niche experience) - A web application alongside your mobile product as a web developer who understands mobile-first thinking If you've been evaluating a flutter developer or a full stack developer who can own your entire product lifecycle, I'd love to learn more about your project. I also regularly consult on architecture decisions for teams choosing between React Native, Flutter, and native (kotlin / swift), so even if your stack isn't finalized, that's a great starting point for a conversation. 🛠️ A Note on Stack Flexibility Over 10+ years as a mobile app developer and web developer, I've worked alongside teams using PHP/Laravel backends, and I understand how to build seamless API layers that connect any backend to a React Native frontend. If your existing backend is built on Laravel, Python, or another stack, that's not a blocker; it's just an integration challenge. 📱 Core Expertise ✔️ React Native & Expo - cross-platform mobile app developer ✔️ Full Stack Developer - Node.js, AWS, Firebase, Supabase ✔️ Web Developer & React Developer - Next.js, REST & GraphQL APIs ✔️ Flutter & React Native comparison consulting ✔️ AI app development - LLM integrations and smart UX ✔️ SaaS MVP launch - from wireframe to 100K users ✔️ App Store & Google Play deployment - 32 apps shipped Let's build something that matters. Drop me a message and tell me what you're working on. I'll give you my honest take within 24 hours.
