Touch-free Access App

An application designed for touch-free access for employees in co-working spaces. I've built a face recognition and verification service using FastAPI which successfully verifies and authenticates a person for access. Worked on liveness detection of a person to verify accordingly.


This tool is built using Python, LangChain, VectorDB, and LLMs, generating the required documents for a project and providing the ability to chat with the data.
