My Portfolio
FAQ
Can you build both Android and iOS apps?
Yes. Flutter and React Native allow me to develop cross-platform applications for Android and iOS from a shared codebase, depending on your project requirements.
Can you add AI to my mobile app?
Yes. I can integrate AI-powered features such as intelligent chat, content generation, AI assistants, recommendations, and API-based AI functionality. The exact implementation depends on your use case.
Can you build an app from my Figma design?
Absolutely. Send your Figma files and requirements, and I can turn the approved interface into a functional mobile application.
Can you connect my app to Firebase, Supabase, or an API?
Yes. Backend and API integration can be included depending on the package and project scope.
Can you publish my app to Google Play or the App Store?
Yes, submission assistance can be added where required. You will need to provide the appropriate developer account access and store information.
What if my app needs more features than the package includes?
No problem. Send me your complete requirements before ordering. I can review the scope and create a custom offer for the additional screens, integrations, or functionality.
Can you fix or improve an existing Flutter or React Native app?
Yes. I can work on eligible existing projects for bug fixing, UI improvements, performance optimization, feature additions, and selected integration work. Please send the current app details before ordering.
