About this Gig
Stuck with a Flutter or React Native crash, build error or unfinished flow? Send the error, reproduction steps and repository details before ordering. I inspect the code and confirm a realistic scope.
I can help with crashes, UI and state issues, API integration, dependencies and build failures in existing apps.
Packages are bounded work sprints:
- Basic: one agreed reproducible bug or build issue scoped to 1 hour.
- Standard: 3 hours for agreed related fixes OR one small feature.
- Premium: 8 hours of prioritized recovery work against an agreed checklist.
We agree on the issue, work allowance and acceptance criteria first. The package does not promise to finish any app or resolve an unlimited bug list. Complex issues may need a separate custom scope.
Delivery includes modified source, verification of the agreed behavior and clear change notes. Revisions correct the agreed work; they do not add features. New apps, major rewrites, paid services and store publishing are excluded. Code and credentials stay private.

FAQ
Can you work on code someone else wrote?
Yes. This gig is for existing Flutter and React Native apps, including abandoned projects. I inspect the code first and confirm which bugs or features fit the selected package.
Is my code kept private?
Yes. Your code stays private and is not shared or reused. Provide access through a private repository invitation or Fiverr attachments; do not send passwords or secret keys.
What do revisions and delivery include?
Revisions cover corrections to the agreed work, not new features. You receive the modified source and handover notes. Major rewrites, new requirements and publishing need a separate scope.
How do you decide what fits in a package?
I review the repository, reproduction steps and expected behavior before ordering. We agree on a task list that fits the 1, 3 or 8-hour allowance. A complex bug may need a custom scope; a sprint is not an unconditional promise to finish an app.
