I will develop a full stack mern saas web application with ai integration
Shaheer Khan
About this gig
AI integration in a MERN stack web application is easy to demo and hard to ship. Streaming, token costs, rate limits and weak retrieval only surface once real users arrive.
My field is Artificial Intelligence. I handle full stack MERN development end to end and build the AI layer inside it, with hands-on work in RAG pipelines and transformer-based NLP.
What you get
- Full stack MERN development React frontend, Express REST API, MongoDB schema design
- Real AI integration chatbots, RAG over your own documents, LLM workflows
- AI software in Python FastAPI when your AI feature needs more than one API call
- Auth & security JWT, protected routes, role-based access
- Source code you own documented, no lock-in
Why me
- AI is my actual field, not an add-on to a web dev gig
- NLP research currently under IEEE conference review
- Live demo of a previous MERN + FastAPI SaaS build on request
Hosting, domain and AI API usage are billed to you directly.
Need AI integration in an existing app, a SaaS development project, or something bigger? Message me and I'll send a custom offer.

FAQ
What makes you different from other MERN stack developers?
AI is my actual field of study, not a service I bolted on. I build the MERN application and the AI layer inside it, including Python/FastAPI services when a feature needs more than a single API call.
Can you add AI features to an app I already have?
Yes, chatbots, RAG over your own documents, or LLM workflows integrated into an existing React/Node codebase. This falls outside the Basic package, so message me with your repo details and I'll send a custom offer priced to the actual work.
What technologies do you work with?
React and Next.js on the frontend, Node.js and Express on the backend, MongoDB for data, Tailwind for UI, JWT for auth, and FastAPI when a Python ML service is needed. Deployment via Vercel, Render or MongoDB Atlas.
What do you need from me before you start?
A feature list or brief, design files or reference sites if you have them, branding assets, any content or copy, API documentation and keys for third-party services, and repository access if we're working inside an existing codebase.
What's included in the packages, and what isn't?
Included: design and development, responsive frontend, database, and full source code you own outright. Not included: hosting, domain and database plan costs, paid third-party services, content writing, logo design, and ongoing maintenance.
Are AI API costs included in the price?
No, OpenAI, Anthropic, Gemini or any paid AI service is billed directly to your own account, since usage scales with your traffic. I'll help you set up the keys and can estimate monthly cost before we start, so there are no surprises.
Is deployment included, and what access do you need?
It's included in Premium and available on request otherwise. I'd need access to your hosting (Vercel, Render or similar), your MongoDB Atlas account, and your domain's DNS settings. Every account stays in your name and ownership.
My project looks bigger than the Premium package, what should I do?
Message me before ordering. I'll review your requirements and send a custom offer with a realistic scope, price and timeline. That works out better for both of us than compressing a large build into a package that doesn't fit it.
