• Automate threat intelligence enrichment realtime event processing and security data visualization.
• Engineer scalable solutions for PCAP analysis network flow monitoring and cloud security event detection.

Forensic Analysis & Threat Intelligence Correlation

• Perform disk memory and network forensics to uncover hidden indicators of compromise (IOCs) and attacker behaviors.
• Correlate multisource logs (firewall EDR web authentication logs cloud telemetry) to reconstruct attack chains and identify attacker footholds.
• Analyze network traffic (PCAP NetFlow proxy logs) to detect exfiltration attempts lateral movement and suspicious patterns.
• Use threat intelligence APIs (e.g. VirusTotal AbuseIPDB) to enrich investigations and automate IOC processing.
