About this gig

Stop your AI from hallucinating. Standard ChatGPT doesn't know your business. I bridge that gap.


Tired of ChatGPT giving generic answers that don't know your business? I build a private AI chatbot that only answers using YOUR documents, your prices, your policies nothing invented, nothing generic. 


What I offer in this service:


* Data ingestion pipelines: I extract text from PDFs, CSV files, or websites and convert it into vector embeddings.


* Vector database setup: Architecture with PostgreSQL (pgvector) or ChromaDB.


* Custom AI model integration: LangChain/LlamaIndex orchestration for accurate, context-aware responses.


* Chat widget & admin dashboard (Standard & Premium): a ready-to-embed chat interface built with React/Next.js, or a full dashboard to monitor conversations and manage your AI's knowledge.


* Secure REST APIs: Clean, documented (Swagger), and production-ready usable by any frontend, mobile app, or third-party tool.


My tech stack: Python, Django/FastAPI, PostgreSQL, Neon DB, LangChain, React/Next.js, OpenAI/Anthropic API.


Let's build an AI chatbot that actually knows your business!
