About this gig

I build custom AI chatbots that answer questions from your internal knowledge PDFs, Word docs, Excel spreadsheets, and PowerPoint presentations.


Powered by RAG (Retrieval-Augmented Generation) + DeepSeek API, the chatbot retrieves accurate information from your documents and generates context-aware answers in real time. Your data stays private with local embedding nothing is shared externally.


Supports multiple formats: PDF, DOC/DOCX, XLS/XLSX, PPT/PPTX.


I deliver clean Python code, a REST API with Swagger docs, and deployment instructions. Fast turnaround, clear communication, and post-delivery support included.
