React Native | SupaBase | Android | iOS | Node.js | Nextjs | Capacitor

Senior React Native | Next.js | Full Stack Developer | iOS | Android | Node.js | Supabase In my most recent project, I converted a production web application into a React Native mobile app, completed the Android and iOS development, and successfully launched it on both the Apple App Store and Google Play Store. I'm currently expanding the same product by developing new backend features with GitHub, VS Code, Node.js, PostgreSQL, REST APIs, and Supabase before merging them into the live iOS and Android applications. 🚀 Imagine having a production-ready React Native mobile app, modern Next.js web application, SaaS platform, multitenant dashboard, or custom business software that works exactly as expected fast, scalable, secure, and built to grow with your business. ❌ No crashing mobile apps. ❌ No broken APIs. ❌ No deployment headaches. ❌ No slow or poorly optimized code. ❌ No frontend and backend synchronization issues. Just clean architecture, responsive user experiences, reliable integrations, and software that's ready for real users. Right now, most businesses struggle with: ❌ React Native apps crashing or failing during Android/iOS deployment ❌ Existing codebases that need debugging, refactoring, or performance optimization ❌ Slow web applications with poor Lighthouse performance ❌ APIs that fail to communicate with frontend or backend services ❌ Firebase or Supabase synchronization issues ❌ Stripe payment integrations that don't work correctly ❌ Authentication problems (JWT, OAuth, Social Login) ❌ Poor UI implementation from Figma designs ❌ Mobile responsiveness issues across different devices ❌ SaaS platforms that become difficult to maintain as they grow ❌ Applications that aren't production-ready ❌ Cloud deployments that constantly fail ❌ Existing applications that need new features without breaking production 👉 That's where I come in. ⚡ Who I Am I'm a Senior Full Stack Developer specializing in React Native, Next.js, React, Node.js, TypeScript, PostgreSQL, Supabase, and modern SaaS application development. I help startups, founders, agencies, and growing businesses build, improve, deploy, and scale production-ready software, from idea to launch and beyond.
