I will develop cross platform mobile apps in react native and expo
Sajjad Amin
About this gig
Looking for a fast, modern cross-platform mobile app for iOS & Android? You're in the right place!
I build high-performance mobile applications using React Native and Expo. Leveraging Expo's ecosystem, I ensure rapid development and seamless app deployments via EAS. Whether you need a brand-new app from scratch or want an existing codebase updated to the latest Expo version, I've got you covered.
# What I Offer:
* Custom iOS & Android App Development
* Figma / Adobe XD to React Native UI conversion
* API Integration & Backends (Node.js, Firebase, Supabase)
* Native features (Camera, GPS, Biometrics, Maps)
* Third-party tools (Stripe/PayPal, Social Auth, Push Notifications)
* Expo Application Services (EAS) build & App Store submission
# Why Expo + React Native?
* Single Codebase: Write once, deploy to Apple App Store & Google Play.
* Faster Delivery: Over-the-air (OTA) updates fix bugs without waiting days for app store approvals.
# My Process:
1. Requirements & UI discussion
2. Clean TypeScript/JavaScript development
3. Rigorous testing on real devices & simulators
4. Delivery of source code & setup guide
NOTE: Please message me before ordering to map out your features

FAQ
Do I need to provide my own Apple and Google Developer accounts?
Yes, you will need to provide your own developer credentials if you want the app published under your name/company. I will guide you through setting up Expo Application Services (EAS) so we can securely build and upload the app directly to your accounts.
Do you write the app in TypeScript or JavaScript?
I build apps using TypeScript by default because it ensures cleaner, scalable, and bug-free code. However, if your existing project is built on standard JavaScript, I can easily work with that as well.
