I will build a custom rag chatbot for your business with langchain

I'm a backend engineer with 4+ years building production systems for enterprise clients (British Telecom, Virgin Media, Liberty Mutual). I build RAG chatbots that are wired into real, scalable backends with proper retrieval, authentication, and deployment so they hold up under actual use.

What you get:

• A custom RAG chatbot trained on your documents (PDFs, docs, websites, knowledge base)
• Accurate, source-grounded answers not hallucinations
• Vector database setup (embeddings + retrieval tuned for your data)
• Clean API or web integration so it fits your existing system
• Optional cloud deployment, ready to scale

Tech I use: LangChain, OpenAI/Gemini, vector databases, Python & Java, Spring Boot, AWS/GCP.

Why me: Most AI freelancers can wire up a demo. I build the backend that demo needs to survive production fault tolerance, auth, CI/CD, real traffic. You get an AI feature you can actually ship, not a prototype that breaks on the second user.
