Developer Tools

Once you’ve established your beginner mind and learned computational thinking, it’s time to master the tools that professional developers use every day. These aren’t just nice-to-haves - they’re essential skills that will make you productive and help you work like a pro.

Think of these as your developer toolkit. Just like a carpenter needs to know how to use a saw, drill, and level, a programmer needs to know Git, the terminal, and testing frameworks.

AI Integration: Modern developers work alongside AI tools to boost productivity and code quality.

Integration with Your Workflow

These tools work together to create a powerful development environment:

Terminal + Git: Navigate your project and manage versions from the command line
Git + Testing: Ensure code quality before committing changes
File Management + Terminal: Efficiently organize and manipulate project files
Shell Configuration + Daily Work: Customize your environment for maximum productivity
AI Tools + Traditional Tools: Combine AI assistance with proven development practices

Professional Context

In the workplace, you’ll use these tools to:

Check out code from team repositories
Create feature branches for new work
Run tests before submitting code reviews
Deploy applications to servers
Debug issues in production environments
Collaborate with designers and product managers
Leverage AI tools for code generation and problem-solving

In personal projects, these tools help you:

Keep track of your progress and experiments
Back up your work automatically
Try new features without breaking working code
Share your projects with others
Build a portfolio of reliable, well-tested code
Accelerate development with AI assistance

Common Developer Workflows

Starting a new feature with modern tools:

1git checkout -b new-feature
2# Use Claude Code to help design the feature
3# Write code with AI assistance
4npm test  # or python -m pytest
5git add .
6git commit -m "Add new feature with AI assistance"
7git push origin new-feature

Daily development routine:

1git pull origin main          # Get latest changes
2# Make changes with AI code assistance
3npm test                     # Run tests
4git status                   # Check what changed
5git diff                     # Review changes
6git commit -am "Fix bug in user authentication"

Optimized shell workflow:

1# With Zsh configuration, use aliases and shortcuts
2gco main                     # git checkout main (with alias)
3gl                          # git log --oneline (with alias)
4gst                         # git status (with alias)

Next Steps

After mastering these developer tools, you’ll be ready for:

Language Fundamentals - Java or Python specifics
Data Engineering - Data processing and analysis
SQL Fundamentals - Database querying and management
