About this gig
Want to add AI to your web app, SaaS, dashboard, or business workflow?
I will integrate AI into your application using ChatGPT API, LangChain, LangGraph, FastAPI, vector databases, Next.js, and production-ready backend architecture.
This is not a basic chatbot widget. I build useful AI features that connect with your business data, documents, APIs, and user workflow.
My process:
- Requirement meeting to understand your business problem
- SRS, AI feature scope, and architecture plan
- UI/UX flow for the AI feature
- Frontend integration with your app
- FastAPI backend, LLM API, RAG, or AI agent development
- Testing, bug fixing, deployment, and documentation
I can build AI assistants, document Q&A, RAG chatbots, AI search, internal knowledge assistants, AI workflow automation, LangGraph agents, and custom AI APIs.
Best for businesses that want accurate, source-aware AI connected to real data.

Accuracy depends on your data quality and use case. I test the AI flow with real scenarios and improve prompts, retrieval, and logic before delivery.

Yes. I provide basic documentation and support for bugs or minor issues related to the delivered scope.
