  • Use your expertise to empower teammates and refine development practices.
  • Collaborate with stakeholders across the business, communicating clearly about trade-offs and solutions.
  • Enhance productivity with AI-assisted tools such as JetBrains, Cursor, Claude Code, and CodeRabbit.
  • Stay current with the latest frameworks, design patterns, and development practices.
