• Implement observability through logging, metrics, alerts, and tracing.
• Participate in troubleshooting, root cause analysis, and production support activities.

CrossTeam Collaboration

• Collaborate closely with application teams, platform engineering, cloud, and security teams.
• Align API design and implementation with enterprise architectural standards.
• Actively contribute to code reviews, design discussions, and technical documentation.
• Promote best practices and a culture of engineering excellence.

Strategic Influence

• Influence API engineering standards, patterns, and best practices across the organization.
• Contribute to architectural reviews and modernization efforts.
• Help drive consistent, scalable, and maintainable cloudnative API solutions.
