I will build an ai powered mobile app with react native and openai
Vasu Sagar
About this gig
Want real AI features in your app, not a chatbot bolted on as an afterthought?
I build React Native apps with OpenAI (or Claude) integrated into the architecture fast, cost-aware, and stable once real users show up.
What you get:
- React Native app for iOS and Android
- OpenAI or Claude integration (chat, voice, or both)
- Secure backend that manages API calls, keys, and cost control
- Conversation history and context/state management
- Prompt design tuned to your actual use case
- Push notifications and offline handling
- App Store and Play Store submission-ready build
How I work:
- We lock the scope AI use case, screens, integrations
- I design the app architecture and the AI/backend layer
- I build the app and tune prompts against real scenarios
- We test cost, latency, and edge cases together
- I deploy and hand over source code and documentation
You get clear communication throughout, not silence until delivery day, plus bug support tied to the agreed scope after launch.
Every AI product is different before ordering, message me your use case, screens, and target launch date.
Third-party AI usage fees are billed separately and are not included.

Hey, I'm Sagar — a full stack developer who specializes in getting AI features into production, not just into a demo. I build the web app, mobile app, or backend around the AI layer (OpenAI, Claude), not the other way around, which is usually where things break for teams that bolt AI on late. 90+ projects, 5.0 rating, real companies. Stack: React, React Native, Node.js, TypeScript, Firebase, MongoDB, PostgreSQL. Send me your idea and I'll tell you honestly what it'll take to build it right.

FAQ
Which AI model do you use?
OpenAI or Claude? Either, depending on your use case and budget — I'll recommend based on your needs.
Who pays for the AI API usage?
You do, billed directly by OpenAI/Anthropic. Those costs aren't included in the gig price.
Can the AI remember previous conversations?
Yes, conversation history and context management is included in Standard and Premium.
Will this work if I get a lot of users?
Yes — I build in cost and rate-limit handling from the start so it doesn't spike your API bill unexpectedly.
Will the AI features keep working smoothly as my user base grows?
Yes — I will build the backend (Node.js and PostgreSQL) to scale alongside your AI features, so performance doesn't drop as more users come in. I also keep an eye on API usage and response times during development to make sure everything stays fast, not just functional.
