Security Operations leader at Hitachi Systems leading a 24x7 SOC and reducing MTTR by 40%.

At Hitachi Systems, I lead SOC operations for enterprise and MSSP clients, managing security engineers across L1, L2, and L3. I built SOAR playbooks that improved threat detection accuracy by 45%.

I redesigned incident response workflows and escalation processes, reducing MTTR by 40% while maintaining 99.9% SLA compliance across multi-client operations. I also lead zero-day response and containment.

At Indian Computer Emergency Response Team (CERT-In), I led incident response and forensic investigations for government and critical infrastructure organizations. I also performed vulnerability assessments and threat intelligence analysis.

Earlier, at Regional Centre for Biotechnology, I managed data security and access reviews for sensitive research data. At Intec Infonet Pvt Ltd, I configured and maintained network infrastructure, including LAN/WAN, routers, switches, and firewalls.
