FAQ
Can you create a fully custom app from the ground up?
Definitely! I'll take your concept and turn it into a fully functional, custom Android app that performs flawlessly.
Do you work with Jetpack Compose and Figma/XD designs?
Yes, I can convert Figma/XD designs to XML layouts or Jetpack Compose UIs.
Do I need to provide a design for reskinning or redesigning?
No, a design is not required unless your app includes complex graphical elements. For simple reskinning or redesigning, I can work with the app's existing design or make improvements based on your preferences.
