FAQ
Can you fix issues related to APIs, Firebase, or backend integration?
Yes! I handle API, authentication, and Firebase-related bugs (Firestore, Realtime DB, Cloud Functions, Auth). I can also debug issues with Supabase, Xano, REST or GraphQL APIs, and third-party SDKs.
Can you fix iOS issues too, or only Android?
Yes
Do you also provide app optimization or refactoring?
Absolutely! Beyond bug fixing, I can improve app performance, reduce bundle size, optimize rendering, and refactor messy or repetitive code for better maintainability and speed.
What if my issue takes longer to fix than expected?
I always analyze your issue first and give a realistic estimate. If it turns out to be more complex, I’ll let you know upfront and propose a fair adjustment — no surprises or hidden fees.
Do you provide support after delivery?
Yes — I offer free after-delivery support (duration depends on the package). If the same issue reappears or you have questions about the fix, I’ll assist you promptly.
