FAQ
Do you offer support after the app is delivered?
Yes, I believe in long-term collaboration. I offer one week of post-launch support to ensure your application is running smoothly and to fix any potential bugs that may arise.
Do you include AdMob integration for monetization?
Yes, I can integrate AdMob into your application to help you monetize your project. This is included in my Premium package, where I ensure all ad units are configured correctly.
How does your AI-powered development workflow benefit me?
I use AI-assisted coding tools to speed up boilerplate and repetitive tasks, but architecture, logic, and final code review are all done manually by me so you get faster delivery without any drop in quality.
Can you help with the Play Store and App Store submission process?
Absolutely. I provide comprehensive support for both Google Play Store and Apple App Store submission, ensuring your app meets all platform guidelines for a smooth launch.
Do you provide the complete source code?
Yes, I provide the full, clean, and well-documented source code for every project, regardless of the package you choose.
