Expo
Expo development, past the point where Expo Go stops helping.
Config plugins, development builds, EAS pipelines, and over-the-air updates that can be rolled back. The parts of Expo that only appear once you need a real binary.

This is where most Expo projects stall: the first build that is not Expo Go.
You are probably here because
If none of these sound like your app, the free call is still the fastest way to find out what does.
eas build is red and the log is four thousand lines of Gradle.
You need a vendor SDK that has no Expo module and no maintainer.
Updates ship over the air, and one of them shipped a crash to everyone at once.
What we set up
Fixed scope, fixed price, agreed before anyone writes code. If something outside this turns out to matter more, we re-scope in the open instead of quietly billing for it.
- Development builds
- A custom dev client so the team stops testing against a runtime the app will never ship on, and native dependencies stop being a launch-week surprise.
- Config plugins
- Native configuration as code: entitlements, Info.plist keys, Gradle settings, permission strings. No more manual Xcode edits that disappear on the next prebuild.
- EAS Build and Submit
- Separate profiles for development, preview, and production, signed on CI and submitted to both stores without a laptop in the loop.
- EAS Update
- Channels tied to runtime versions, with rollout and rollback, so an over-the-air update is a decision you can reverse instead of a broadcast you cannot.
- Bare workflow
- Prebuild with the native projects under version control, when the app has genuinely outgrown managed. Quoted separately after we see the native dependencies, because a migration with unknown native code is not something anyone can fix-price up front.
- Monorepo and CI
- Expo inside a pnpm or Turborepo workspace, with typecheck, lint, build, and Detox end-to-end runs on EAS Workflows all executing before anything reaches a store.
Price
One number, agreed before we start.
A pipeline-only engagement fits here. A full app build is the Production-Ready scope at up to $7,500.
We have shipped our own products to real users: Mira on the iOS App Store and ariex.fit in public beta. There are no rescue case studies in the portfolio yet, and we are not going to claim there are some under NDA.

Start with the free callQuestions we get asked first.
Anything not answered here is worth twenty minutes on a call.
Expo or bare React Native?
Expo, for nearly every new app. The managed workflow stopped being a limitation once config plugins and development builds landed, and EAS removes an entire category of signing and CI work. Bare is worth it when you have deep native code of your own that fights prebuild, and that is rarer than the internet suggests.
Can Expo apps use native code?
Yes. With a development build and a config plugin, an Expo app can use any native dependency, including SDKs with no Expo support at all. Expo Go is the limitation people run into, not Expo.
Is EAS Update safe to use in production?
It is, if channels are pinned to runtime versions and you have a rollback path. It is not safe as a way to skip store review for changes that need review. We set the boundary up explicitly so nobody has to guess which changes can go over the air.
Can you migrate our bare React Native app to Expo?
Usually yes, and the win is CI and signing rather than the framework itself. We audit first, because a migration is only worth doing if the native code you already have survives prebuild without a rewrite.
Who owns the EAS account and the signing credentials?
You do. We work inside your Expo organisation and your developer accounts. Nothing about the release pipeline should depend on us still being around.
Other things we do.
