Frequently Asked Questions

Common questions about my work and services

I primarily use React Native with Expo for cross-platform development, TypeScript for type safety, Firebase for backend services, and integrate AI APIs like OpenAI's GPT-4 Vision for intelligent features.

Yes! All my apps are built cross-platform using React Native and Expo, which means they run natively on both iOS and Android from a single codebase. This ensures consistent quality across platforms.

Absolutely! I have extensive experience integrating AI capabilities including OpenAI's GPT-4 Vision for image analysis, natural language processing, and computer vision features into mobile applications.

My process follows four key phases: Discovery (understanding requirements), Design (UI/UX prototyping), Development (building with React Native/Expo), and Deployment (launching on App Store & Google Play with ongoing support).
