Automated daily rankings of GitHub Certifications leaders across different regions worldwide.

The rankings are automatically updated daily via GitHub Actions:

1. Data Collection: Fetches certification data from Credly API for all countries worldwide

   • Collects GitHub certifications from official GitHub organization badges
   • Includes Microsoft-issued GitHub certifications (migrated from GitHub in 2024)
   • Uses parallel processing for fast data retrieval
   • Optimized handling for large countries (India, USA, Brazil, UK)

2. Smart Filtering: Ensures ranking accuracy

   • Expired certifications are automatically excluded from counts
   • Only valid (non-expired) certifications count toward rankings
   • Top 30 candidates per country are validated for accurate results
   • 96% reduction in API requests with intelligent candidate selection

3. Company Information: Enriches rankings with professional context

   • Company data fetched from public Credly user profiles
   • Displayed alongside name and certification count in rankings
   • Updated during ranking generation for top performers only

4. Data Storage: All certification data in the datasource/ directory

   • Individual CSV files per country (e.g., github-certs-brazil.csv)
   • Metadata tracking for update timestamps and optimization

5. Ranking Generation: Creates TOP 10 rankings for each region

   • Regional rankings: Brazil, Americas, Europe, Asia, Africa, Oceania
   • Global ranking with top performers worldwide
   • Automatic markdown file updates with latest data

This project tracks ALL GitHub certifications from two sources:

1. GitHub Organization Badges - All certifications issued directly by GitHub on Credly

   • Core Certifications: Foundations, Actions, Advanced Security, Administration, Copilot
   • Partner Credentials: Migrations, AzureDevOps Migrations, Advanced Security Partner Delivery
   • Sales Badges: FY26 Sales Professional, Revenue Motions, Platform, Copilot, etc.
   • Professional Badges: Tech Sales Professional, Sales Professional
   • Any other badge issued by the GitHub organization

2. Microsoft-Issued Badges - GitHub certifications transitioned to Microsoft Learn

   • GitHub Foundations (Microsoft Certified)
   • Other GitHub certifications now issued via learn.microsoft.com
   • Microsoft Certified: DevOps Engineer Expert (related DevOps certification)

Note: All badges from the GitHub organization on Credly are counted, not just the core certifications. As of 2024, GitHub migrated some certification issuance to Microsoft Learn. Additionally, the Microsoft Certified: DevOps Engineer Expert certification is included due to its relevance to GitHub workflows and DevOps practices.

• Expiration Filtering: Only active, non-expired certifications are counted
• Automatic Validation: Certification expiration dates are checked against current date
• Example: A user with 15 total badges but 3 expired will show 12 valid certifications
• Daily Updates: Rankings refresh daily to reflect newly issued and expired certifications

You can manually trigger the rankings generation:

1. Go to the Actions tab
2. Select "Generate GitHub Certifications Rankings"
3. Click "Run workflow"

# Fetch data for a single country
python3 fetch_country.py "Brazil"
python3 fetch_country.py "United States"

# Fetch all countries in parallel
python3 fetch_data.py

# For countries with thousands of certified users
python3 fetch_large_country.py "India"
python3 fetch_large_country.py "United States"

# Generate all regional and global rankings
python3 generate_rankings.py
