Nice to have:

• Defining features, technical specifications, and architecture based on business requirements.
• Participating in client meetings, advising on technical choices, and maintaining strong relationships.
• Enhancing code quality through code reviews, automated testing, and fixing bugs. (No need to worry about slip-ups – our CI/CD won’t let any “DROP DATABASE production” happen 🙃).
