Hello, I worked on updating the mobile application on React Native, where I upgraded the Expo SDK from 47 to 52, tested on Android/iOS, 100% bug-free.

Do you have any specific dependencies that cause the most problems during the update?

I suggest we get in touch, I will consult you for free on the technical side and we will create a development plan + I will tell you about my team!

Hello! 👋 I represent 256Devs. We will take on an urgent migration of RN + Expo from 49 to Expo SDK 54, ensuring compliance with Google Play API Level 35 and Xcode 16; we will go through the completed audit, update dependencies (Navigation/Reanimated/Firebase), resolve native conflicts, check Auth0 + GraphQL, and perform regression tests on key flows. Please send the repository, audit/checklist, and deadline — we will synchronize the plan.

EXPO-URGENT
Hi! This week I also migrated from version 33 to 36 of the API SDK, which triggered a lot of dependency updates - including React Native and several other libraries. It turned out to be quite a time-consuming task.

EXPO-URGENT

Hello,
I am interested in supporting your Expo migration.
I have strong experience with React Native and Expo, including upgrades to SDK 52–54.
I have worked with complex production apps and handled step-by-step migrations across major versions.
I am comfortable updating dependencies, resolving native build issues, and ensuring full compliance for both Google Play and App Store.

I have experience with Apollo, React Navigation, Reanimated, Firebase, and other common libraries.
I also worked with Auth0 and GraphQL, so verifying backend connectivity will be smooth.
