Basic Qualifications:

• Document your bugs, experiments, and fixes—it helps the whole team and makes you a more thoughtful developer.
• Monitor logs and system metrics to help identify performance bottlenecks, errors, or unusual behavior.
• Use version control systems (like Git) to commit code, review changes, and stay in sync with team branches and main builds.
• Contribute to database migrations, schema updates, and data seeding for staging and production environments.
