I will develop your ios and android app using react native and expo


About this gig
Need a polished, production-ready mobile app that runs smoothly on iOS and Android?
You're in the right place.
I'm Hamza, a full stack developer with 3+ years building live, high-traffic apps. I have developed and delivered cross-platform production apps in React Native/Expo for a real estate platform, a life-critical healthcare app, online marketplaces, and other domains.
Most React Native freelancers only build the frontend. I build both sides: the screens your users see, plus the database, API, and admin dashboard behind them, so your app actually works end to end.
What I can build:
- Full apps from idea to MVP
- Real estate, marketplace, booking, and utility apps
- Authentication, push notifications, real-time sync
- REST API, Firebase, Supabase or custom backend (Node.js/Laravel)
- Admin dashboards to manage content without code
- Fixes and upgrades to existing apps
Why work with me:
- Building live production apps right now, not just past projects
- Full stack: frontend, backend, and database in one hire
- Fast, direct communication and clean, documented source code
I guarantee high-quality, satisfying work.
Eager to work together soon. Questions? Let's chat.

FAQ
Do I need to have a design ready before I order?
No. If you have a Figma file or reference app, I will build to match it exactly. If you do not have a design yet, I can design a clean, modern UI for you as part of the Standard or Premium package, or as an add on to Basic.
What is the difference between the three packages?
Basic is a focused MVP with one core feature, ideal for testing an idea quickly. Standard adds real backend connectivity so your app can store and retrieve live data. Premium is a complete product: custom backend, admin dashboard, and app store submission support.
Do I get the full source code?
Yes, on every package. You will receive clean, commented code with a short explanation of the folder structure, so any developer can maintain it going forward, not just me.
Will my app work on both iPhone and Android from a single codebase?
Yes. That is the core benefit of React Native and Expo. I build once and it runs natively on both platforms, which saves you significant time and cost compared to building two separate native apps.
Which backend options do you support?
I work with Firebase and Supabase for faster builds, and Node.js or Laravel with MySQL for projects that need a fully custom backend or already have an existing database. I can also connect your app to a backend you already have.
Do you handle App Store and Google Play submission?
Yes, submission assistance is included in the Standard and Premium packages and available as an add on for Basic. I will prepare the build, guide you through developer account requirements, and handle the submission process with you.
What do you need from me to get started?
A short description of your app idea, your target platforms, any design references or Figma files, and any specific integrations you need such as payments, maps, or chat. The more detail you share upfront, the faster and smoother the build.
What happens if I need changes after delivery?
Each package includes a set number of revisions during development. After final delivery, minor bug fixes related to the original scope are covered for a short window, and I offer ongoing maintenance plans if you want continued support.
Can you take over or fix an existing React Native app?
Yes. I regularly work inside existing codebases to fix bugs, improve performance, or add new features. Please share access to the repository and a description of the issues so I can review before quoting.
How fast can you start?
I can typically begin within 24 to 48 hours of order confirmation. For urgent timelines, message me first and I will let you know if expedited delivery is possible for your specific scope.
