  ; ensure inclusive, user-centered interfaces.

• Event-driven features
  : integrate with Kafka for event management where required.

• Operability & telemetry
  : instrument front-end services with AWS telemetry for performance and reliability.

• Modern delivery
  : manage work in Jira/Confluence
  ; use Git Hub with trunk/Git Flow; implement CI/CD pipelines with automated tests and security scans.

• Quality & performance
  : optimise for speed, accessibility, and maintainability; apply caching and JSON binding best practices.
