AI Applicant Tracking System (ATS) is a production-ready software application that brings artificial intelligence to recruitment workflows. Built on FastAPI and React, this full-stack ATS uses OpenAI GPT-4 for intelligent resume parsing, sentence transformers for semantic job-candidate matching, and machine learning algorithms for automated applicant ranking. You get complete source code with the ability to deploy, modify, and commercialize the platform for your own business or clients.
 
The system includes a React 18 frontend with TypeScript and TailwindCSS, a FastAPI backend with SQLAlchemy ORM, and PostgreSQL database with pgvector extension for vector similarity search. Core capabilities include natural language candidate search, multi-format resume uploads (PDF, DOCX, TXT), job posting management, application pipeline tracking, and real-time dashboard analytics. The AI engine calculates multi-factor match scores based on skills overlap, experience levels, education requirements, location compatibility, and deep semantic similarity between job descriptions and candidate profiles. Training data uses synthetic data generation to improve model coverage and protect user information.
 
Key features: AI-powered resume parsing extracts structured data from unstructured documents. Semantic matching creates vector embeddings for intelligent candidate-job pairing beyond keyword matching. Automated ranking scores and sorts applicants using configurable weighting factors. Natural language search lets recruiters query candidates in plain English. The system generates AI-driven screening questions tailored to each job posting and provides detailed match score breakdowns explaining why candidates fit specific roles.
