AI Career Copilot: A Full-Stack Job-Seeking Assistance System Based on Large Language Models

AI Career Copilot is a full-stack job-seeking assistance system based on Large Language Models (LLM) and computer vision technology, designed to provide job seekers with a one-stop intelligent solution from resume analysis to career planning. Core functions include automatic resume scoring, personalized learning roadmaps, real-time career guidance, etc., solving the problem of single-function traditional job-seeking tools and forming a complete job-seeking closed loop.

In the highly competitive job market, job seekers face challenges such as resume screening, skill matching, and interview preparation. Traditional job-seeking assistance tools have single functions and are difficult to form a complete closed loop. AI Career Copilot emerged as the times require, providing a one-stop intelligent solution through LLM and computer vision technology.

The project adopts a layered architecture design, with technology selection balancing efficiency and scalability:

• Backend: Python3.13 + Flask + Jinja2
• AI Core: Google Gemini Pro API + LangChain
• Data Persistence: SQLAlchemy ORM (SQLite for development, PostgreSQL switchable for production)
• Frontend: Tailwind CSS + GSAP
• Security: Flask-Bcrypt + Flask-Login + RBAC permission control Each module has clear responsibilities, facilitating expansion and maintenance.

Modular Code

AI services are isolated into tool modules:

• utils/ats.py: Gemini interface encapsulation
• utils/auth.py: permission logic
• utils/parser.py: document processing
• utils/roadmap.py: learning path generation Improves code maintainability

Applicable to:

• Fresh graduates: Understand resume competitiveness and clarify skill improvement directions
