Hi, I'm Balaji Viswanathan

AI/DataEngineer | LLMs & Agentic AI Systems | RAG Pipelines

I design and build intelligent AI systems - from autonomous agentic workflows to production-ready RAG pipelines. Currently completing my Post Graduate degree in AI & ML at Nipissing University, Ontario, Canada.

What I Work On

  • Agentic AI Systems — Multi-agent workflows with planning, tool use, memory, and self-reflection using LangGraph
  • RAG Pipelines — Hybrid retrieval (semantic + keyword + metadata) with FAISS, ChromaDB, Pinecone
  • LLM Engineering — Prompt engineering, fine-tuning, and integrating OpenAI, Ollama, and Hugging Face models
  • AI Automation — ETL-integrated LLM agents, data quality copilots, and intelligent document analysis

Tech Stack
