About this gig

Need an AI assistant that answers your customers, your team or your users automatically, using your own data?


I build custom AI chatbots with Python, using OpenAI or Anthropic models. I currently work as a backend developer, where I built an AI assistant that queries a company database and answers questions in natural language.


What I can build:

- Chatbots that answer from your documents, FAQs or database (RAG)

- Assistants integrated with your website, WhatsApp or internal systems

- REST APIs (FastAPI) so the chatbot connects to anything

- Handoff to a human agent when needed


What you get:

- Clean, documented and tested code

- Setup instructions and support after delivery


Please message me before ordering so we can confirm the scope and pick the right package.
