• Implement feature flagging (LaunchDarkly) for controlled rollouts and safe release strategies.

• Conduct thorough code reviews, maintain documentation, and contribute to wiki-based architecture and design docs.

• Support production deployments, change management (CHGs), post-deployment validation, incident response, and root cause analysis (RCA).

• Leverage AI-assisted development tools (GitHub Copilot) to accelerate delivery.
