FAQ
Do you build apps with Kotlin or Java?
I'll recommend Kotlin for new projects (Google's preferred language) but can work in Java if that matches your existing codebase.
Can you work with my existing project/codebase?
Yes, send me your project files or repository access and I'll review scope before we start.
Do you handle Play Store publishing?
Yes, this is included in the Premium package, or available as an add-on for Basic/Standard.
What do you need from me to get started?
A brief description of your app or feature, any design files (Figma/screenshots) if available, and access to any existing code or backend/API docs.
