The Engineer Who Gets Pulled In

When your systems go down, I get them back up. I diagnose high-impact issues in authentication, event ingestion, and distributed workflows—and I lead the teams coordinating the resolution.

I work across multi-tenant, multi-node SIEM deployments ingesting thousands to hundreds of thousands of events per second.

I excel at multi-node failure analysis, cross-team escalations, and building the analytics platforms and automations that prevent recurring problems at scale.

I bring order to chaotic incidents by clarifying scope, sequencing actions, and driving cross-team alignment.
