I will build, update or fix your react native app for ios and android
Georgi M
About this gig
Need a React Native app built, extended or repaired? I take on React Native work for iOS and Android, from a first MVP to fixing an app that no longer builds.
What I can do:
New MVP apps with login, navigation and forms; payments on request.
New features, screens and API integrations in your existing codebase (TypeScript, Redux, MobX).
Bug fixes, crashes, React Native upgrades and store build problems.
A Node.js / NestJS backend when your app needs one.
Why me: 8 years as a software engineer. I built ev1000 solo, end to end: a white-label EV-charging platform with a React Native app for iOS and Android, its backend, charger-to-cloud over OCPP 1.6J and a payment provider integration (auth, retries, reconnection, reconciliation). I was also a Senior Software Engineer at SoftConstruct (2022-2025), building realtime backends with server-side validation and recovery after disconnects.
How I work: all in writing, so requirements stay on record. A written plan before I start, progress updates every 2-3 days, and every decision documented.
I'm new on Fiverr, so message me before ordering: describe your app and I'll reply with a clear scope and package.

FAQ
Can we have a call?
I work in writing only, through Fiverr messages. It keeps every requirement and decision on record: you get a written plan before work starts, progress updates every 2-3 days and a short note for each decision. Send screenshots, screen recordings or docs and I'll answer in detail.
Can you work on my existing React Native app?
Yes. Share the repo (or a copy), the React Native version and what is wrong or missing. I read the codebase first, try to reproduce the issue on iOS and Android (for device-specific bugs I'll ask for logs or a recording), and send a written fix plan before changing code.
Which package should I choose?
Basic is one bug or one small feature. Standard is a set of up to 3 features, an API integration or a React Native upgrade. Premium is a new MVP. If you're unsure, message me first and I'll recommend one or send a custom offer.
Do you publish the app to the App Store and Google Play?
I prepare signed release builds and help you through submission. The store accounts should be yours (Apple Developer and Google Play Console), so you keep ownership. Approval is Apple's and Google's decision; if review notes concern the app's code or build, I help fix them.
Can you build the backend too?
Yes. For ev1000 I built the React Native app, the backend, charger-to-cloud over OCPP 1.6J and the payment integration myself. I work with Node.js, NestJS and MongoDB, or connect the app to your existing API.
Can you add payments to my app?
Often, as a Standard order or an add-on to Premium (Premium does not include payments by default). On ev1000 I integrated a payment provider end to end: auth, retries, reconnection and reconciliation. Tell me the provider and what you sell, and I'll confirm before you order.
What do you need from me to start?
A short description of the app or the problem, repo access or a copy of the code, designs or screenshots if you have them, and API docs or backend details. Everything else is settled in the written plan before work begins.
Do I get the source code?
Yes. You get the full source code in your repository (or as an archive) with written setup notes, so another developer with the right tools and your store/signing access can build and run the app.
