An upgrade branch
Dependency and native-project changes for the agreed scope, with documented replacements or breaking changes that need a product decision.

Stuck after an RN upgrade, build error, dependency conflict, or Expo SDK issue?

The written proposal defines the target versions, affected platforms, and verification needed for your app. Use it as the handoff checklist.
Dependency and native-project changes for the agreed scope, with documented replacements or breaking changes that need a product decision.
Results for the agreed iOS and Android builds, the checks performed, and any remaining limitations. Your QA owner validates app-specific workflows before release.
A change summary, setup and build instructions, and outstanding decisions. Your team retains control of release approval and production deployment.
Repository access under NDA, reproducible build steps, a technical contact, and a QA owner with a testing plan. Agree on access to test accounts and any signing or build services during scoping.
Confirm separately: new features, a full rewrite, backend work, store submission, ongoing maintenance, and a comprehensive security audit. They are not implied by an upgrade engagement.
These are the problems teams bring to us every week.

Book a free 30-minute call. We'll assess your situation, tell you exactly what needs fixing, and give you an honest scope — no commitment required.

A failed build, an Expo SDK change, and a native-module migration need different plans.
Align the SDK, dependencies, config plugins, and native builds around an agreed target.
See the Expo upgrade scope →Assess third-party libraries and custom native modules, then scope the changes and verification.
See the migration scope →Compare an internal project, an independent specialist, an agency, and a scoped rescue.
Compare your options →| Criteria | Do It Yourself | RN Rescue |
|---|---|---|
| Typical turnaround | Weeks of senior dev time reading changelogs and migration guides | Typically 1–4 weeks, set in the proposal |
| Dependency conflicts | Fix one dependency, break three others | We've fixed hundreds of broken React Native upgrades |
| Native build tooling | Xcode and Gradle tooling breaks with cascading errors | We own the iOS and Android build pipeline end-to-end |
| Impact on feature roadmap | Feature roadmap stalls while devs learn as they go | Your team keeps shipping features while we handle the upgrade |
| Native bridge & platform issues | Native bridge and platform-specific issues with no clear fix | Upgraded codebase, documented changes, clean handoff |
| Total cost | Weeks of senior dev time lost | One fixed quote, agreed before work starts |
We fix build failures, dependency conflicts, Hermes and TurboModules crashes, Expo SDK upgrade issues, native module incompatibilities, CocoaPods and Gradle build errors, and cascading failures from multi-version React Native upgrades. If your app built before and doesn't build now, we'll find out why on the call and scope the fix in a written proposal.
A single build failure, dependency conflict, or minor version bump usually takes 1–2 weeks. A multi-version upgrade or full dependency overhaul usually takes 2–4 weeks. Severely outdated apps are scoped individually, and the timeline is part of the proposal.
We assess your codebase before starting and quote a fixed price for that scope. If we encounter unexpected complexity mid-project, we discuss options with you before proceeding — no surprise charges.
We request read/write access to your git repository (GitHub, GitLab, or Bitbucket). We sign NDAs before accessing any code and work in isolated branches. We can work within your existing security requirements.
After a free call and a look at the codebase, we send a proposal with a fixed scope and one fixed quote. A single build failure, dependency conflict, or minor version bump is a small scope. Multi-version upgrades, full dependency overhauls, and New Architecture migrations are larger. We'll need code access, a QA resource who can work alongside us, and a testing plan.
Every day your team spends on a broken upgrade is a day they're not shipping features.
