About this gig

Looking for a custom AI chatbot, RAG system, or LLM application?

I will build a reliable AI solution that can understand your documents, retrieve relevant information, and generate grounded answers using modern Generative AI and RAG technologies.

What I can build:

AI chatbots for PDF and document-based Q&A

Retrieval-Augmented Generation (RAG) systems

Multi-document knowledge assistants

Agentic AI and Agentic RAG systems

Semantic search and vector database solutions

LLM-powered applications using LangChain and Google Gemini

FastAPI REST APIs with Swagger/OpenAPI

Dockerized AI applications and deployment-ready solutions

My workflow includes: document ingestion, chunking, embeddings, vector search, retrieval, evidence filtering/ranking, grounded response generation, and source/page attribution where required.

I can also integrate Qdrant or ChromaDB, add API authentication and monitoring, and prepare your application for cloud deployment.

Whether you need a simple document chatbot or an advanced Agentic RAG assistant, I will build a clean, scalable solution tailored to your requirements.

Please message me before ordering so I can understand your project requirements.
