AI Chatbot Development (RAG, OpenAI, Claude, Agents)Himanshu Kumar
Custom AI chatbots and assistants that actually know your business. I build grounded, secure conversational AI on top of your documents, databases and tools, from prototype to production.
What you get
RAG chatbot over your docs, PDFs, websites or databases (LangChain, vector search, embeddings)
LLM integration with OpenAI GPT, Anthropic Claude, Groq or Hugging Face models
Agentic workflows with tool use: search, SQL generation, summarization, charts
Voice and real-time chat (OpenAI Realtime, Whisper, WebSockets)
Website widget or full chat UI (React/Angular) with a FastAPI backend
Guardrails, prompt engineering, query auditing and usage/latency monitoring
Why work with me
Built enterprise AI assistants at BCG: conversational analytics on Snowflake, meeting-intelligence with RAG on AWS OpenSearch, and agentic research platforms.
Built data collector chatbot which surfs through internet and saves bank's published data into a sharepoint folder, extracts data points, builds ppt over one prompt.
Production focus: security (SSO/OAuth2), cost control and reliable answers
Live demo of my own portfolio chatbot available. Visit himanshuportfolio.in
No cost hypercare support for one week post deployment.
Share your use case and data sources and I will propose the best approach.
