I will build an ai powered web app using mern stack and openai or gemini API
Abdul Haseeb
About this gig
I build full-stack, AI-powered web applications using the MERN stack (MongoDB, Express, React, Node.js), integrated with OpenAI or Google Gemini.
Whether you need a smart chatbot embedded in your product, a document-analysis tool that reads and answers questions about your files (RAG), an AI-powered dashboard, or a complete AI SaaS platform I design and build it end-to-end.
What I deliver:
- Custom AI features: chatbots, content generation, summarization, recommendations, document Q&A
- Full MERN architecture: React frontend, Node/Express backend, MongoDB database
- Integration with OpenAI (GPT models) or Google Gemini your choice
- Clean, documented, scalable code you fully own
- Authentication, dashboards, and admin panels when needed
- Deployment support (Vercel, Render, AWS, or your preferred host)
Why work with me:
- Hands-on experience shipping real AI-integrated applications (see portfolio/demo links)
- I explain trade-offs (cost, latency, model choice) instead of just writing code
- Clear communication and realistic timelines no over-promising
Send me a message with your idea before ordering if you're unsure which package fits I'll help you scope it.

My Portfolio
FAQ
Do you provide the OpenAI/Gemini API key?
No — you provide and pay for your own API key so you retain full control of usage and cost. I can help you set one up if needed.
What tech stack do you use exactly?
MongoDB, Express.js, React, and Node.js on the backend/frontend, integrated with the latest available OpenAI or Google Gemini models depending on your preference and budget.
Can you build a RAG (Retrieval-Augmented Generation) system?
Yes, document ingestion, chunking, embeddings, and a vector database (e.g., Pinecone, Chroma) so the AI can answer questions grounded in your own content
Will I own the code?
Yes, full source code and documentation are delivered and are yours outright.
Do you handle deployment?
Yes, available as an add-on or included in the Premium package (Vercel, Render, AWS, etc.).
How do you handle API costs and rate limits?
I implement usage safeguards (rate limiting, error handling, cost-aware prompting) and explain the trade-offs so you're not surprised by billing.
