About this service

Summary

I help startups and entrepreneurs bring their app ideas to life using React Native (Expo) for cross-platform development. By combining agile development practices with powerful backend solutions like Firebase or Supabase, with features like real-time data, push notifications, and secure user authentication. Whether you need a prototype, MVP, or production-ready app, I deliver clean, maintainable code and user-friendly interfaces tailored to your vision.

Process

Step 1: Discovery & Requirements We’ll begin with a short call or written brief to understand your goals, target audience, features, and any design references or inspiration.

Step 2: Wireframing & Planning I’ll outline the app structure and key screens. If needed, we’ll finalize user flows and UI mockups before development begins.

Step 3: App Development (Frontend) Using React Native (Expo), I’ll develop the mobile app interface and ensure cross-platform compatibility for iOS and Android.

Step 4: Backend Integration I’ll connect your app to backend services using reliable BaaS tools (Firebase, Supabase, or similar)—including features like auth, database, push notifications, and storage.

Step 5: Testing & QA The app will go through internal testing on multiple devices, ensuring smooth functionality and performance.

Step 6: Delivery & Handoff You’ll receive the final source code, build files, and optionally a guide for deployment to the App Store and Google Play.

Optional: Post-launch Support Need help after launch? I offer ongoing maintenance, feature updates, and bug fixes on request.

FAQs

Will the app work on both iOS and Android?
Yes! I use React Native (Expo), which allows me to build and maintain a single codebase that runs on both platforms.
What backend tools do you use?
I typically use Backend-as-a-Service tools like Firebase, Supabase, or AWS Amplify to handle things like user authentication, real-time data, and storage. However, i'm open for building a separate backend application for your needs.
Do you help with app store submission?
Yes, I can assist with submitting your app to both the Apple App Store and Google Play, if needed.
Can you update or maintain an existing app?
Absolutely. I can help refactor, update, or add new features to your existing React Native project—let’s talk about what you need!
