  • Proven experience in system monitoring, incident management, and large-scale system optimization.
  • Excellent troubleshooting skills and the ability to perform root cause analysis in complex technical environments.
  • Maintain observability through monitoring, logging, and alerting tools (e.g., Prometheus, Grafana, ELK).
