Message

At Positive Technologies, I led business analysis and delivery for MaxPatrol SIEM features, translating enterprise SOC needs into requirements and functional specifications. I drove analysis for an AI-based behavioral anomaly detection module that identified up to 85% of attacks missed by traditional SIEM correlation rules.

I also led analysis for Event Card UX enhancements and integrations that helped SOC operators handle incidents up to 2x faster. Earlier, I supported a desktop-to-web migration at Security Code completed within 1 year, and at Digital Security (ERPScan) I led analysis for a security scanning product developed from scratch over 2 years.
