Technical Architecture and Core Methods

Tech Stack

The backend uses FastAPI to build high-performance API services; data storage and retrieval employ the FAISS vector search engine, supporting multiple index types to balance speed and recall rate.

RAG Architecture

A core design pattern that combines external knowledge bases with LLM to improve answer accuracy, solve knowledge timeliness and hallucination issues, and achieve job matching at the semantic level.

Vector Search Principles

Job descriptions and resumes are converted into high-dimensional vector embeddings, and matching results are found via cosine similarity calculation; FAISS provides efficient index structures and search algorithms.

Role of LLM

It parses complex job requirements (skills, experience, etc.), generates explanations of matching results, personalized job-seeking advice, and resume optimization suggestions; it collaborates with vector search to form an intelligent pipeline.

Practical Application Value and Evidence

  • Efficiency Improvement: Compared to traditional keyword matching, semantic matching finds more potential suitable candidates, reducing the screening workload for HR.
  • Developer Reference: Provides a runnable reference implementation to help learn RAG system design, vector database optimization, LLM-search integration, and FastAPI best practices.
