Why people hire me for an app
I write the React Native app myself. You talk to the person who will take it through both stores.
One person on the product
Interface, APIs, logins, payments and the store release. The same engineer from the first call.
Both stores from one codebase
React Native and Expo so iOS and Android ship together, without two native teams.
The product pieces
Accounts, memberships, bookings, payments and notifications, then a release people can download.
Australian hours
Scope, builds and store questions happen on Sydney time, not through an overnight relay.
Store release
From a working build to the app stores
I take apps through TestFlight, Play testing, App Store Connect and Google Play Console, not just a demo. Di Lorenzo / My Fit Spot and feels@home are two examples: memberships, bookings and payments on iOS and Android. If you want the longer notes, read how I would hire an AI or React Native developer in Sydney and React Native fitness apps in Sydney. A platform beside the app is custom SaaS development; a website is web development.

Mobile apps
React Native, both stores, one engineer
The work is the scope, the React Native UI, the APIs, auth, payments and the App Store and Play release. A website or SaaS product comes later, only if the app needs one.

What is included
What the app build covers
React Native for iOS and Android, plus APIs, auth, payments, notifications and the store release. I design and build it. You keep the repository.
The product
Memberships, bookings, payments and push notifications in one codebase, then I stay on after the stores approve the release.
The process
We agree the scope first. I build in stages: discovery, UI, APIs, then both stores. A multi-tenant website is a separate piece of work if you need it.
Examples
A production app, not a wrapped website
What people usually need
One real app for memberships, bookings and payments. Not a website squeezed into a phone frame, and not two separate native teams.
How I build it
React Native for both stores: APIs, subscriptions and a release people can download. If a past app is close to yours, the links below are the ones to open.
How it works
From the brief to both app stores
One codebase
iOS and Android from one React Native codebase, including the store submission. There is no second team after the first call.
What is included
- React Native iOS apps from Sydney
- Android apps in the same codebase
- Cross-platform Expo builds
- Membership & SaaS mobile products
- API, payments and auth integrations
- Ongoing support from one Sydney engineer
Discover & Define
Users, systems, Apple and Google developer accounts, the timeline and what a successful store release looks like are written down before design starts.
Includes
- Scope written before design
- Feature plan before React Native starts
- Member and trainer journey mapping
- Store-account and release requirements you keep
Design & Prototype
Journeys, wireframes and a prototype, including the store listing screens, are agreed before production code starts.
Includes
- UX for iOS and Android members
- Wireframes tied to the store build
- Interactive prototypes to validate
- Design sign-off before I code
Build & Test
The React Native code is tested on TestFlight and a Google Play internal track: real devices, crash checks and the store review guidelines.
Includes
- TestFlight builds for iOS beta testers
- Google Play internal / closed testing tracks
- Device QA against store review guidelines
- Crash and performance checks before submit
Launch & Deploy
I handle App Store Connect and Google Play Console: listing copy, screenshots, a phased release and crash monitoring until real users can open the app.
Includes
- App Store Connect submission from Sydney
- Google Play Console release with me on it
- Store listing metadata and screenshots
- Phased release plus crash monitoring after go-live

How it is delivered
