Methodology

Identity Verification with Selenium

City Assist automates professional ID verification using Selenium for browser interactions, which verifies IDs on official portals. This helps ensure authenticity at scale, especially for specific professions such as nursing.

Aadhaar Verification with PaddleOCR

The platform uses PaddleOCR for Aadhaar card verification. By extracting and matching text from Aadhaar images, City Assist validates user-provided details, enhancing security and reducing manual effort.

Advanced Search with MongoDB Vector Search and Google Embeddings

City Assist employs vector-based search with MongoDB and Google Embeddings, enabling efficient and nuanced matching of user queries with household help profiles. This provides more accurate results compared to basic conditional filtering.

Frontend Development with Streamlit

Streamlit provides a fast, responsive UI for City Assist, enabling users to quickly search, filter, and verify profiles with minimal lag, enhancing the overall experience.

City Assist combines vector search with MongoDB, OCR verification with PaddleOCR, and Selenium automation, creating a user-friendly platform for reliable and fast household help matching.
