About this gig

Build intelligent, modern web apps using MERN Stack, NestJS and OpenAI.

I specialize in creating smart, scalable full-stack web applications powered by AI. Using React for the frontend and NestJS or ExpressJS for a powerful backend, I integrate tools like OpenAI, Langchain, and Pinecone to create responsive, data-aware experiences.

From AI chatbots and document-based assistants to custom dashboards and APIs I bring your vision to life with clean UI, optimized backend logic, and optional deployment to Vercel or AWS.


What I Can Deliver

  • Responsive React frontend
  • NestJS or Express backend
  • OpenAI API integration (chat, embeddings, Q&A)
  • Langchain + Pinecone setup for smart search
  • Authentication (JWT/session)
  • File upload (e.g. PDF AI Q&A)
  • Deployment on Vercel or AWS


NOTE: Message me before placing your order so I can guide you to the perfect package.
