Veelgestelde vragen
What do you need from me to start working?
I need your Flutter project source code (ZIP or GitHub link), a clear description of the problem, any error messages/screenshots, and reproduction steps. Having this upfront helps deliver faster.
Do you fix Supabase and Firebase bugs?
Yes! I fix both Firebase and Supabase-related issues, including auth, database queries, and integration-related bugs.
Can you help with app build errors and Play Store issues?
Yes — I can fix build errors (Gradle, signing, SDK, build failures) and help with Play Store release problems. Just mention the issue when you contact me.
Can you add new features to an existing app or only fix bugs?
Yes — you can choose bug fixes or feature additions (dark mode, offline support, localization, maps, offline caching, etc.).
How long does it take to fix a bug?
Delivery time depends on complexity. Simple UI or logic bugs are usually fixed in 1–2 days, while advanced or backend-related issues take 2–5 days. I’ll give a precise estimate after reviewing your case.
Do you test the app after fixes or new features?
Yes — I test on multiple screen sizes (and OS versions if possible) to ensure functionality, responsiveness, and stability.
What if the bug isn’t fixed after delivery?
I offer free revisions if the issue still exists or wasn’t fully resolved. Just let me know what happened and I’ll continue fixing it.
