About this gig

Want an AI assistant that actually knows your business? I build custom AI chatbots and RAG (Retrieval-Augmented Generation) assistants that answer questions from your own documents, website and data, accurately and with sources.


I'm a Full-Stack DevOps Engineer with 6+ years of experience. I recently built a RAG assistant that cut a client's manual data lookup time by about 70%.


What I can build:

- Website chatbots for support, sales and FAQs

- Internal knowledge assistants for PDFs, docs, Notion or databases

- RAG pipelines with vector databases and source citations

- OpenAI / GPT integrations inside your existing web app or SaaS

- Admin panels to upload and manage your knowledge base


Tech: OpenAI API, LangChain, vector databases, Node.js, Python, React, PostgreSQL, MongoDB, Docker and AWS.


You get clean, documented source code, secure handling of your data and API keys, and deployment on your own cloud or server.


Please message me before ordering so we can confirm your data sources, use case and the right package.
