System Observability: Monitor the health, throughput, consumer lag, and error rates of Kafka-based systems to ensure reliable data delivery.
Incident Management: Investigate production issues, participate in root cause analyses, and implement preventive measures to systematically improve system resilience.
Technical Quality & Mentorship: Drive code reviews, share technical knowledge, reduce technical debt, and mentor junior engineers.
