About this gig
Need a reliable backend, or want to add AI to your app? I build secure Node.js APIs and connect them to OpenAI, Claude or Gemini, so your web or mobile app gets real AI features.
I am a MERN and React Native developer with 6+ years of experience. I have built backends for real products, including a hospital management system with real time patient monitoring and an online film festival platform, and I use AI APIs in my work.
AI integrations:
- AI chatbot that answers from your own content (docs, FAQ, products)
- Text generation, summaries, translation and smart search
- AI agents that call your APIs and automate tasks
- Streaming replies, usage limits and cost tracking
Backend APIs:
- REST APIs for React, Next.js and React Native apps
- Login with JWT, user roles and permissions
- MongoDB database design and file uploads
- Real time features with Socket.io
You also get:
- API keys kept safely on the server, never in the app
- Swagger docs and a Postman collection
- Deployment help and setup notes
Message me with your idea and I will suggest the right package and timeline.

I build complete products: React Native mobile apps for iOS and Android, React and Next.js web apps, and the Node.js and MongoDB backend behind them. 6+ years of JavaScript and full-stack development. I lead the Digital Technologies and Software Sector at Baku State University, work as Lead Developer on a hospital management system, and built and published my own Islamic platform app on the App Store. I have taught React and React Native for 4+ years, so I write clean code and explain things simply. Message me before ordering and I will reply with a clear plan.

FAQ
Can you connect the API to my existing frontend or app?
Yes. I work on both sides, so I can connect the API to your React, Next.js or React Native app, or hand over clear documentation so your frontend developer can do it easily.
What counts as an endpoint?
One route and method, for example GET /products or POST /login. A simple CRUD resource like products usually needs 4 to 5 endpoints. Send me your feature list and I will count them for you.
Where will the API be hosted?
On your own server or a cloud platform of your choice. In the Premium package I handle the deployment and database setup. Hosting costs are paid by you, and I explain the options first.
Which AI models can you integrate?
OpenAI (GPT), Anthropic Claude and Google Gemini. I recommend the best fit for your task and budget. API usage is billed by the provider to your own account, and I set it up so costs stay under control.
