FAQ
Which platforms do you develop apps for?
I develop for both iOS and Android. For iOS, I use Swift and SwiftUI for native performance. For cross-platform solutions, I use Flutter and React Native, which allow a single codebase to run smoothly on both iOS and Android saving you time and cost without sacrificing quality.
Can you publish my app to the App Store and Google Play?
Yes. I provide App Store (Apple) and Google Play Store submission support. I'll prepare all assets, metadata, and submission requirements. Note: you'll need a developer account on each platform ($99/year for Apple, $25 one-time for Google).
Do you build AI-powered mobile apps?
Yes. I can integrate AI features into your mobile app including GPT-powered chatbots, AI-driven recommendation engines, image recognition, voice assistants, and other intelligent automations using APIs like OpenAI, Google AI, and LangChain.
Can you integrate payment gateways into my app?
Yes. I integrate popular payment solutions including Stripe, PayPal, and in-app purchases (Apple Pay / Google Pay). This is included in Standard and Premium packages and can be added to the Basic package as an add-on.
What information do I need to share to get started?
Please provide: Your app idea and core features Target platform (iOS, Android, or both) Any reference apps or designs you like Your timeline and budget I'll review everything and send you a detailed proposal before you place an order.
Can you work on an existing app or just build from scratch?
Both. I can build your app from scratch, or I can update, enhance, fix bugs, add new features, or improve performance on an existing iOS or Android app. Share your current code or APK/IPA and I'll assess it quickly.
How do you ensure the quality of the app before delivery?
Every app goes through a structured quality assurance process before delivery: Functional testing across multiple device sizes and OS versions UI/UX consistency checks API and Firebase connection testing Performance and load optimization Security review for authentication and data handling
