The problem
What you're seeing
You're stuck on an old React Native release, the upgrade-helper diff is 5,000 lines, and every dependency wants a different version.
How we fix it
Our approach
We map the upgrade matrix, patch native modules, fix Hermes / Fabric / new-architecture gotchas, and ship the upgrade behind a release branch with full regression QA.
What you get
Concrete deliverables, no fluff
Every engagement ends with measurable, documented outcomes — no black-box agency reports.
Reproduction of the bug or perf issue on a real device
Implementation behind a PR you review
Verified fix on iOS and Android (real hardware, not just simulator)
Release notes + App Store / Play Store update checklist
Tooling we use
Industry-standard stack, no proprietary lock-in
