I will build or fix your vibe coded mobile app
Yuvraj Sonawane
About this gig
Your Flutter or React Native app may compile, yet still crash, break on certain devices, lose data offline, or fail store review.
I will diagnose the root cause, fix the issue, and finish the parts that are blocking a reliable release. I work with existing projects and improve what is there without rebuilding everything.
I can help with crashes, build errors, incomplete features, authentication, API and database issues, state management cleanup, responsive and adaptive layouts, offline behavior, notifications, payments, performance, and App Store or Play Store readiness.
This gig is for fixing, finishing, and productionizing an existing mobile projectnot starting a new app from scratch.
I am a senior product engineer with 11+ years in software development and 6+ years focused on Flutter and mobile products. I have worked across Android and iOS, production fintech apps, accessibility, responsive UI, APIs, and backend systems. I can take ownership from diagnosis through tested handover.
Message me before ordering with the repository or workspace, target devices, current problem, and expected outcome. Larger rescues and unclear scopes are best handled with a custom offer.

FAQ
Can you work with an existing Flutter or React Native project?
Yes. I can join an existing Flutter or React Native codebase, preserve working parts, and improve the areas that are blocking release.
Can you fix an app that compiles but is not production ready?
Yes. I can investigate crashes, device-specific issues, incomplete flows, API problems, performance, offline behavior, and release configuration.
Can you help with App Store or Play Store readiness?
I can fix build and configuration issues, prepare release builds, and work through technical preflight items. You keep ownership of your store accounts and submit when you are ready.
Will you rewrite the whole app?
Usually no. I first isolate the root cause and keep what works. If a larger refactor is necessary, I will explain the reason and propose a staged plan.
What access do you need?
I usually need repository or workspace access, reproducible steps, logs, test builds, and any relevant API or design notes. Use an appropriate secure method; never paste passwords or private keys into Fiverr messages.
