I will build an ai powered native mobile app with rag or chatbot
Ziya Ogul
About this gig
Do you want to add a reliable AI experience to your React Native or Expo mobile app?
I build AI-powered mobile features for iOS and Android, including chat assistants, RAG-based document search, text transformation flows, personalised AI experiences and safe API integrations.
I have hands-on experience shipping cross-platform AI products using OpenAI and Anthropic APIs. My work focuses on more than a chat screen: I design the user flow, context handling, failure states, retries and practical backend integration so the feature behaves reliably in a real product.
What I can help you build:
- AI chat or assistant experiences
- RAG and document-based Q&A
- OpenAI or Anthropic API integration
- Text generation, rewriting and summarisation flows
- User-specific context and personalised responses
- Error handling, retries and fallback behaviour
- React Native, Expo, Supabase and Firebase integration
Please message me before ordering if you need a complex AI agent, large document collection, custom backend architecture or App Store deployment. I will review the scope and create the right custom offer for your product.

FAQ
Can you integrate APIs and third-party services?
Yes. I can integrate REST APIs and third-party services such as payment systems, authentication providers, AI APIs, maps, notifications, analytics, and other external services.
Can you add subscriptions or in-app purchases?
Yes. I can implement mobile subscriptions and in-app purchases, including solutions using RevenueCat and Google Play subscriptions.
Can you publish the app to the App Store and Google Play?
Yes. I can help prepare and configure the application for production release and guide you through the App Store and Google Play submission process.
I only have an idea. Can you still build the app?
Absolutely. You don't need to have a complete technical specification. You can share your idea, and we can define the features, architecture, and development scope together.
Can you work with my existing application and add new features?
Yes. I can work with an existing React Native, Expo, React, Next.js, or backend project to fix bugs, improve performance, integrate new features, or extend its functionality.
Do you provide source code?
Yes. The source code is provided according to the package and project agreement.
Can you build an MVP for my startup?
Yes. I can help transform your idea into a functional MVP with the essential features needed for testing and launching your product.
What do you need from me before starting?
Ideally, I need your app idea, required features, preferred design or references, and any existing assets or backend/API information. If you don't have everything prepared, that's okay—we can define the requirements together before development.
