ATS Master Resume Compiler | Jay Patel Portfolio

Project Overview

An automated career acceleration utility developed in Python. This tool aggregates a central JSON data structure representing my entire master professional history, parses it, and dynamically compiles optimized, single-page, ATS-compliant HTML/CSS resumes and cover letters. It is designed to bridge technical scripting with strategic career development.

The Problem

Traditional resume editing is incredibly manual and error-prone. Tailoring qualifications for specific roles usually means managing multiple Word documents, losing layout constraints, and failing automated applicant tracking systems (ATS) due to non-standard elements. Developers and coordinators need a programmatic way to manage, compile, and maintain a single source of truth.

What I Did (Technical Action)

Designed a modular Python CLI pipeline. Stored my master experiences in a single, robust JSON database file. Developed data extraction modules to filter experience nodes based on target roles. Programmed an HTML/CSS template engine utilizing standard inline CSS spacing, relative padding ratios (10.5px body font), and semantic elements. Integrated a headless Chrome compiler via CLI hooks to print vector PDFs with zero browser headers/footers, maintaining exact single-page constraint boundaries.

Architected a programmatic candidate application suite. Integrated National Occupational Classification (NOC) schemas (such as Transportation Coordinators and Customer Service Supervisors) directly into the compiler. The tool analyzes job descriptions, extracts priority keywords, and selects the most relevant professional metrics from my master history, compiling optimized single-page submissions automatically.

Why This Stands Out

This project proves I don't just "write resumes" — I build systems. It demonstrates clean Python data structuring, JSON parsing, automation pipeline design, and strict rendering controls. It showcases an developer mindset that immediately automates operational bottlenecks.

Rather than applying blindly, I treated my career development as an operations workflow optimization problem. By structuring a single data source and automating delivery, I proved that I can design compliant administrative systems that boost output while maintaining 100% precision.
