We handle dependency upgrades, build failure rescues, and security audits in 2–4 weeks — each quoted as one fixed price. Senior engineers only, North America-based, shipping React Native since 2016.
Senior Engineers working with React Native since 2016. North America-based. No outsourcing.
We own the entire upgrade from start to finish — dependency updates, breaking changes, native module fixes, build verification, and handoff. Your team keeps shipping features.
We handle this every week. Fixed scope, fixed price, senior engineers.
Book a free 30-minute call. We'll look at your situation, tell you exactly what needs fixing, and give you an honest scope — no commitment required.

| Criteria | Do It Yourself | RN Rescue |
|---|---|---|
| Typical turnaround | Weeks to months of senior dev time spent reading changelogs and migration guides | Typically 2–4 weeks, fixed scope |
| Dependency conflicts | One dependency upgrade breaks three others | We've handled hundreds of dependency conflicts — we know the gotchas |
| Native build tooling | Xcode and Gradle build tooling breaks with cascading issues | We own the iOS and Android build pipeline end-to-end |
| Impact on feature roadmap | Feature roadmap stalls while your team learns as they go | Your team keeps shipping features while we handle the upgrade |
| Native bridge & platform issues | Platform-specific issues with no clear path forward | Upgraded codebase, documented changes, coordinated handoff |
| Total cost | Weeks of senior dev time diverted from features | One fixed quote, agreed before work starts |
We work best with teams who recognize themselves in this:
Most of our clients are engineering managers or CTOs at companies between 50–500 employees whose mobile team is stretched thin — and who need this handled, not taught.
We'd rather tell you upfront:
If that's you, the free vulnerability scanner and security checklist are a good starting point — no cost, no commitment.
We work through secure repository access (GitHub, GitLab, Bitbucket). We sign NDAs before accessing any code and can work within your existing security requirements. All work happens in isolated branches.
Yes. Expo managed workflow apps are usually smaller scopes, because Expo's upgrade tooling handles much of the complexity. Expo bare workflow or ejected apps are scoped like standard React Native projects.
We handle native iOS and Android code, including custom modules, CocoaPods, and Gradle configurations. Complex native integrations add scope, and the fixed quote reflects that before work starts.
We assess your codebase before starting and quote a fixed price for that scope. If we encounter unexpected complexity during the project, we'll discuss options with you before proceeding—no surprise charges.
We update your code to work with new API signatures, replace deprecated methods, and fix compatibility issues. For breaking changes that require product decisions (e.g., a library removed a feature), we'll flag these for your team to decide.
Yes. We can migrate your app to React Native's New Architecture including Fabric renderer and TurboModules. Whether it belongs in the same fixed quote depends on your current setup and third-party library compatibility, which we check before quoting.
We handle build verification and basic functionality checks, but you'll need a QA resource on your team to validate app-specific features and business logic. We deliver a fully upgraded, building app—your team confirms it works as expected before deploying.
Our developers are based in North America. You'll work with senior engineers in your time zone who communicate clearly and understand enterprise requirements—no offshore handoffs or communication delays.
Book a free 30-minute call. No pressure, no sales deck — just a straight conversation about your app and what it would take to fix it.
Every week of delay adds more advisories to triage, more engineer hours, and more features your roadmap is waiting for. The upgrade won't get easier — but it can get done.
