Mobile Application Development from Existing PWA
Budget: $5,000 – $10,000 CAD
# React Native / Expo Developer Needed to Build iOS + Android App from Existing PWA
We are looking for an experienced **React Native / Expo developer** to build and launch our mobile app for **iOS and Android**.
The web/PWA version of the app is already built. The backend APIs already exist. The design, screens, flows, and functionality are already defined in the current PWA.
This project is **not** a full app concept from scratch. The job is to rebuild the existing mobile/PWA experience as a proper native mobile app using React Native / Expo, connect it to our existing APIs, and prepare it for launch on the Apple App Store and Google Play Store.
## Project Scope
You will be responsible for:
* Building the iOS and Android app using **React Native / Expo**
* Matching the existing PWA design, layout, screens, and user flows
* Connecting the app to our existing backend APIs
* Implementing authentication and session handling
* Building reusable mobile UI components based on the current app design
* Implementing all required forms, validation, navigation, and role-based flows
* Ensuring the app works properly on common iPhone and Android screen sizes
* Preparing production builds for iOS and Android
* Assisting with App Store and Google Play submission
* Providing basic handoff documentation
## Important Requirements
* Do not redesign the app unless specifically asked.
* Do not rebuild the backend.
* Do not create new APIs unless approved.
* Do not add new features outside the agreed scope.
* The goal is to match the current PWA as closely as possible in native mobile form.
* Code must be clean, maintainable, and structured for future development.
## Preferred Tech Stack
* React Native
* Expo
* TypeScript
* Existing REST APIs
* iOS and Android production builds
* App Store / Google Play deployment experience
## Ideal Candidate
You should have:
* Strong React Native / Expo experience
* Experience converting an existing web/PWA product into a mobile app
* Experience working with existing APIs
* Experience publishing apps to Apple App Store and Google Play
* Good communication and clean development practices
* Ability to work quickly without drifting from the approved scope
Please do not apply with a generic response. We are looking for someone who understands that the design, backend, and workflows already exist. This is primarily a mobile rebuild and launch project.
## Application Questions
Please include answers to the following:
1. Have you built and launched React Native / Expo apps on both iOS and Android?
2. Have you converted an existing PWA or web app into a native mobile app before?
3. Will you use the existing APIs only, without rebuilding the backend?
4. Can you match an existing UI closely without redesigning it?
5. What is your estimated timeline for the first working beta build?
6. What do you need from us before starting?
7. Please share 2–3 examples of mobile apps you have built or launched.
## Deliverables
* Working iOS app
* Working Android app
* Source code
* Production-ready builds
* App Store submission support
* Google Play submission support
* Basic setup and handoff documentation
We are ready to move quickly with the right developer.
