FAQ
Can you fix an app developed by another developer?
Yes. Many clients come to me after their previous developer became unavailable or left the project unfinished. I can review the existing code, identify the issues, and continue development, provided the source code is available.
Can you add new features to my existing app?
Yes. I can implement new features such as payment gateways, authentication, Firebase integration, push notifications, chat systems, maps, booking systems, subscriptions, API integrations, and many other custom functionalities.
Can you help publish or update my app on Google Play or the App Store?
Yes. I can assist with preparing your app for release, fixing common submission issues, updating existing apps, and helping ensure your application meets the requirements for Google Play and the Apple App Store.
