I don't just write React Native code. I ship apps people actually use. 1M+ downloads. 30+ countries. 200+ projects. 100% Job Success.
Most clients come to me when their React Native app is stuck, broken, or half-built and nobody else could finish it. Or when they need a mobile app developer who handles everything from first screen to App Store and Google Play launch. Some come with an MVP idea and need a react native developer who moves fast without cutting corners. Others come because their react native mobile app has performance issues or complex integrations nobody else could solve. I've been doing this for 8+ years, delivered 200+ projects, and the apps I've built as a mobile app developer now serve 590K+ users across 30+ countries.
WHAT I BUILD
As a react native developer and react native engineer I cover the full mobile lifecycle across 200+ shipped products:
✦ React Native mobile apps with Expo and CLI for iOS and Android
✦ React Native Expo MVPs shipped from first screen to App Store and Google Play
✦ React Native Firebase integrations — auth, Firestore, real-time sync, push notifications
✦ React Native Supabase backends and React Native Node.js APIs that scale with the product
✦ AI mobile app development with OpenAI API, real-time features, and on-device intelligence
✦ In-app purchases, RevenueCat subscriptions, AdMob, deep linking, and push notifications
✦ Native Swift and Kotlin modules and android kotlin integrations when cross-platform isn't enough
✦ App Store and Google Play submissions including rejections, TestFlight, and review handling
I work as a react native full stack developer so clients don't need to hire two separate people. Firebase, Supabase, and Node.js on the backend — one team, one codebase, one point of contact.
INDUSTRIES
I've shipped products as a mobile app developer and mobile application developer across multiple verticals. In Fintech and Crypto I built a trading platform with 590K+ registered users and 2M+ monthly visitors. In Healthcare and Wellness I delivered apps with 100K+ downloads, a 4.9 App Store rating, and users across 30+ countries. In EdTech I shipped language learning and trivia apps that together reached 1M+ downloads. I've also delivered E-commerce, SaaS MVPs, Hospitality, and On-demand platforms:
✦ Fintech and Crypto — 590K+ users, 2M+ monthly visitors
✦ Healthcare and Wellness — 100K+ downloads, 4.9 App Store rating, 30+ countries
✦ EdTech — 1M+ downloads across 30+ countries
✦ E-commerce and Marketplace
✦ SaaS and Startup MVPs
✦ Hospitality and On-demand Services
WEB AND FULL STACK
On the web side I work as a react developer and front end developer building platforms with React, Next.js, and Node.js. I've delivered react nextjs products, full stack developer react node systems, and full stack developer ai projects with LLM integrations and OpenAI workflows. I've worked alongside Vue and Angular codebases and helped clients migrate from WordPress to modern React stacks. On larger projects I work as a web developer delivering both mobile and web from the same team.
Clients who need an app developer ios android with full backend ownership also work with me on ios android developer projects. I collaborate with flutter developer and android developer teams when needed, and I structure codebases that a python developer or backend node.js team can extend later.
WHY CLIENTS WORK WITH ME
✦ 8+ years as a react native developer and mobile app developer — 200+ projects, 1M+ downloads, 30+ countries
✦ React native full stack developer — mobile frontend and backend in one engagement
✦ Fast at complex bugs, App Store rejections, and performance issues others couldn't fix
✦ Clear written communication and honest timelines, no surprises
✦ Available after launch for support, new features, and scaling
WHAT CLIENTS SAY
"Michael is an outstanding react native developer — skilled, reliable, and delivers clean, efficient code."
"Succeeded on complex React Native bugs where others failed."
"Exceeded our expectations."
