Why Your GitHub Projects Matter More Than Your Resume

In the competitive tech job market, your GitHub repositories often speak louder than bullet points on a resume. While resumes list qualifications, GitHub projects demonstrate them in action.

"When evaluating candidates, I spend three times longer reviewing their GitHub projects than their resume. Their code tells me what they can actually do, not what they claim they can do." — Jennifer Marsh, Engineering Director at TechFusion

According to a Stack Overflow developer survey, 75% of hiring managers report that they review candidates' code samples before making interview decisions, and GitHub is the primary platform where they look for these samples.

A strategically built GitHub portfolio doesn't just supplement your resume—it can completely transform your job prospects by providing irrefutable evidence of your capabilities.

### Example: Setting Up a Testing Infrastructure

```javascript
// Example Jest configuration (jest.config.js)
module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'jsdom',
  setupFilesAfterEnv: ['<rootDir>/src/setupTests.ts'],
  collectCoverageFrom: [
    'src/**/*.{js,jsx,ts,tsx}',
    '!src/**/*.d.ts',
    '!src/**/*.stories.{js,jsx,ts,tsx}',
    '!src/index.tsx',
  ],
  coverageThreshold: {
    global: {
      statements: 80,
      branches: 70,
      functions: 80,
      lines: 80,
    },
  },
};

// Example test file (src/components/Button/Button.test.tsx)
import React from 'react';
import { render, screen, fireEvent } from '@testing-library/react';
import Button from './Button';

describe('Button component', () => {
  test('renders with correct text', () => {
    render(<Button>Click me</Button>);
    expect(screen.getByRole('button')).toHaveTextContent('Click me');
  });

  test('calls onClick handler when clicked', () => {
    const handleClick = jest.fn();
    render(<Button onClick={handleClick}>Click me</Button>);
    fireEvent.click(screen.getByRole('button'));
    expect(handleClick).toHaveBeenCalledTimes(1);
  });

  test('is disabled when disabled prop is true', () => {
    render(<Button disabled>Click me</Button>);
    expect(screen.getByRole('button')).toBeDisabled();
  });
});

Quality Assurance Workflows

Implement professional QA processes:
