🚀 LeverParser

A Python library for parsing resumes with Lever ATS compatibility. Extract structured data from resumes with high accuracy.

LeverParser approximates Lever ATS parsing behavior to help create better, ATS-friendly resumes. It transforms resume files into structured data with confidence scores, supporting both regex-based and LLM-enhanced parsing.

✨ Why LeverParser?

• 🎯 Lever ATS Compatible: Approximates Lever's parsing behavior for ATS optimization
• 🔒 Privacy-First: Parse resumes locally without sending data to external services
• ⚡ Lightning Fast: Process resumes in under 2 seconds with high accuracy
• 🤖 LLM Enhanced: Optional integration with OpenAI/Anthropic for complex formats
• 📊 Confidence Scores: Know how well each section was parsed
• 🔧 Developer-Friendly: Simple API, comprehensive documentation, and type hints throughout

🚀 Quick Start

Installation

pip install leverparser

Basic Usage

from leverparser import ResumeParser

# Initialize the parser
parser = ResumeParser()

# Parse a resume file
resume = parser.parse('resume.pdf')

# Access structured data
print(f"Name: {resume.contact_info.name}")
print(f"Email: {resume.contact_info.email}")
print(f"Experience: {resume.get_years_experience()} years")
print(f"Skills: {len(resume.skills)} found")

# Get detailed work history
for job in resume.experience:
    print(f"• {job.title} at {job.company} ({job.start_date} - {job.end_date or 'Present'})")

Parse Text Directly

resume_text = """

resume = parser.parse_text(resume_text)
print(f"Parsed resume for: {resume.contact_info.name}")

🎯 Key Features

📋 Comprehensive Data Extraction

• Contact Information: Name, email, phone, LinkedIn, GitHub, address
• Professional Experience: Job titles, companies, dates, responsibilities, locations
• Education: Degrees, institutions, graduation dates, GPAs, honors
• Skills: Categorized by type (programming, tools, languages, etc.)
• Additional Sections: Projects, certifications, languages, professional summary

🔍 Smart Pattern Recognition

• Multiple Date Formats: "Jan 2020", "January 2020", "01/2020", "Present", "Current"
• Flexible Formatting: Handles various resume layouts and section headers
• International Support: Recognizes global phone formats and address patterns
• Robust Parsing: Gracefully handles incomplete or malformed resumes

📈 Confidence Scoring

Every extraction includes confidence scores to help you assess data quality:

from pyresume.examples.confidence_scores import ConfidenceAnalyzer

analyzer = ConfidenceAnalyzer()
analysis = analyzer.analyze_resume_confidence(resume)

print(f"Overall Confidence: {analysis['overall_confidence']:.2%}")
print(f"Contact Info: {analysis['section_confidence']['contact_info']:.2%}")
print(f"Experience: {analysis['section_confidence']['experience']:.2%}")

Word	.docx	pip install python-docx
Text	.txt	Built-in support

🏗️ Architecture

PyResume uses a modular architecture for maximum flexibility:

pyresume/
├── parser.py          # Main ResumeParser class
├── models/
│   └── resume.py      # Data models (Resume, Experience, Education, etc.)
├── extractors/
│   ├── pdf.py         # PDF file extraction
│   ├── docx.py        # Word document extraction
│   └── text.py        # Plain text extraction
└── utils/
    ├── patterns.py    # Regex patterns for parsing
    ├── dates.py       # Date parsing utilities
    └── phones.py      # Phone number formatting

🔧 Advanced Usage

Batch Processing

Process multiple resumes efficiently:

from pyresume.examples.batch_processing import ResumeBatchProcessor

processor = ResumeBatchProcessor()
results = processor.process_directory('resumes/', recursive=True)

# Generate reports
processor.generate_csv_report('analysis.csv')
processor.generate_json_report('analysis.json')
processor.print_analytics()

Custom Skill Categories

Extend the built-in skill recognition:

# Load and customize skill categories
from pyresume.data.skills import SKILL_CATEGORIES

# Add custom skills
SKILL_CATEGORIES['frameworks'].extend(['FastAPI', 'Streamlit'])

# Parse with enhanced skill detection
resume = parser.parse('resume.pdf')

Export Options

Convert parsed data to various formats:

# Convert to dictionary
resume_dict = resume.to_dict()

# Export to JSON
import json
with open('resume.json', 'w') as f:
    json.dump(resume_dict, f, indent=2, default=str)

# Create summary
summary = {
    'name': resume.contact_info.name,
    'experience_years': resume.get_years_experience(),
    'skills': [skill.name for skill in resume.skills],
    'companies': [exp.company for exp in resume.experience]
}
