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.
Designed for recruiting agencies, HR departments, staffing firms, and SaaS entrepreneurs building recruitment platforms. The perpetual license permits you to build and operate a materially new product including commercial SaaS services. Complete documentation covers installation, API endpoints, deployment strategies, and customization guides. Requires basic technical knowledge for setup: Python 3.9+, Node.js 18+, PostgreSQL 13+ with pgvector, and an OpenAI API key (not included; ongoing API costs apply). The codebase totals over 4,000 lines of Python backend code, 470+ lines of TypeScript frontend code, plus comprehensive training datasets and setup scripts.

(b) open-source, disclose, or provide access to the source code of the software application except to Buyer’s employees and contractors who are bound by written confidentiality obligations;
(c) use the software application, or any substantially similar version of it, to create or offer a competing developer tool, template, starter kit, boilerplate, clone, or other product whose primary value is substantially the same as the software application itself; or
(d) remove any proprietary notices contained in the software application.
Buyer IP. As between the parties, Buyer owns Buyer’s branding, content, data, and original code that Buyer independently creates for Buyer’s end product, excluding the software application and any portion derived directly from it.
