- Use AI coding assistants (e.g., GitHub Copilot, Windsurf/Devin) effectively and responsibly.

- Use Git for version control and participate in code reviews and branching workflows.
- Build and package applications using Maven; containerize and run services with Docker.
- Collaborate in agile ceremonies, contribute to estimations, and communicate progress and risks clearly.
- Troubleshoot issues across the stack (UI, API, database, container/runtime) and contribute to root-cause analysis.
