FAQ
Why should I build my app with React Native and Expo?
React Native allows us to build a single codebase that compiles to native iOS and Android apps, cutting development time and maintenance costs by 50%. Expo provides fast development, Over-The-Air (EAS) instant updates without waiting for app store reviews, and seamless native performance.
Can you publish my app to the Apple App Store and Google Play Store?
Yes! I handle the full build process using EAS Build, configure app identifiers, certificates, icons, and splash screens, and guide you through submission and review until your app is live on both stores.
Can you convert my Figma, Adobe XD, or Sketch designs into a mobile app?
Absolutely. I specialize in 1:1 pixel-perfect mobile implementation. Every screen, component, spacing, animation, and responsive tablet layout will precisely match your Figma file.
Which backend and database solutions do you support?
I integrate modern backends including Supabase (PostgreSQL), Firebase (Firestore, Auth, Cloud Functions), custom Node.js/Express REST APIs, and GraphQL with secure JWT authentication and role-based access.
Will I own 100% of the mobile app source code?
Yes, 100%. Upon project completion, you receive full intellectual property ownership and the complete source code transferred directly to your GitHub account or delivered as a clean repository.
