Your mobile app, from idea to the stores.
I design and build iOS and Android apps connected to your platform: website, Shopify store, business database. One codebase, a solid API behind it, and I take care of publishing on the App Store and Google Play.
My apps in production Street Art App · Caviste
01.Sound familiar?
- We have a website, our customers want an app.
Your users come back often, but they miss notifications, the camera, the map around them.
- The agency shipped the app, then vanished.
An app lives on: new iOS and Android versions, changing store rules, fixes.
- Two native apps means twice the budget.
A shared iOS and Android codebase cuts development and maintenance costs.
- Our app isn't connected to anything.
It needs to talk to your back office, your store, your customer accounts.
02.What I deliver
The app and everything behind it: I'm a backend developer first, so the API, the data and the connectors are part of the project, not another quote.
- iOS and Android app
React Native and Expo: one codebase, a native interface on both platforms.
- API and back office
A custom Symfony API, or a connection to your existing platform: Shopify, CRM, business database.
- Native features
Camera and scanning, geolocation and maps, push notifications, Sign in with Apple and Google.
- Subscriptions and in-app purchases
Premium plans sold through the App Store and Google Play.
- Store publishing
Listings, screenshots, developer accounts, getting through Apple and Google review.
- Over-the-air updates
Fixes and content pushed straight to phones, without going through store review again.

06.FAQ
Why React Native rather than native?
One codebase for iOS and Android means it costs less to build and to maintain. For the user, the app is still native: camera, maps, notifications, smooth scrolling.
How much does a mobile app cost?
It depends on the number of screens, the native features and the back office you need. We start by defining a useful, focused first version together, with a precise quote.
Do you handle App Store and Google Play publishing?
Yes: store listings, review submission, answers to any rejection. The app is published on your own developer accounts, so it belongs to you.
What happens after launch?
I offer ongoing support: fixes, compatibility with new iOS and Android versions, new features. Many fixes can be pushed over the air, without waiting for store review.
Can my app connect to my Shopify store?
Yes. That is my core backend expertise: catalog, customer accounts, orders, loyalty. See Shopify connectors.
