## Overview

SkillEngine is a career-market analytics app: users explore job demand, compare their skills with market requirements, and get obsolescence predictions and learning roadmaps; they can also upload job data and ask a career-advice chatbot. The React client talks to a FastAPI backend that uses MongoDB and an NLP engine. The tree also contains a separate Spring-based authentication service. Some feature coverage and links come from the README and SOURCE INDEX; unsampled route behavior and frontend calls are not inferred beyond those references.

Main entry points: [`frontend/src/services/api.js`](https://github.com/ankubisht987/skill-obsolescence-and-curriculum-relevance-analytics-engine/blob/main/frontend/src/services/api.js) (API client), [`backend/main.py`](https://github.com/ankubisht987/skill-obsolescence-and-curriculum-relevance-analytics-engine/blob/main/backend/main.py) (API entry), [`backend/database/connection.py`](https://github.com/ankubisht987/skill-obsolescence-and-curriculum-relevance-analytics-engine/blob/main/backend/database/connection.py) (MongoDB), [`login/src/main/java/com/project/login/controller/UserLoginController.java`](https://github.com/ankubisht987/skill-obsolescence-and-curriculum-relevance-analytics-engine/blob/main/login/src/main/java/com/project/login/controller/UserLoginController.java) (Java auth controller)
