Monitoring and alerting tuned so incidents surface before customers feel them.
SRE at Cynet · Israel
Yonatan Harrison
Site Reliability Engineer. I keep production calm — monitoring that catches incidents before customers do, infrastructure as code instead of risky manual work, and AI agents that speed up root-cause analysis.
How I work
Reliability is a habit, not a heroic weekend.
PProactive.
AAutomated.
Terraform, Kubernetes and ArgoCD over clicking. Less toil, less alert noise.
⌘AI-assisted.
Elastic ML anomaly detection and AI agents for faster root-cause analysis.
⇄Cross-team.
The person R&D, Product, Sales and infrastructure call when production is on fire.
