What I'm looking for

I'm looking to continue building and optimizing SIEM and security monitoring capabilities, investigating incidents, improving detection coverage, and strengthening security operations in complex enterprise environments.

I've deployed, upgraded, and optimized QRadar and Splunk SIEM environments for major banking clients at Systems Limited, improving scalability and performance by 40%.

I led Splunk SIEM deployment at Meezan Bank from the ground up and onboarded more than 400 log sources across systems, applications, and network infrastructure. I also resolved a critical Windows authentication logging failure affecting 450+ servers at HBL within 48 hours.

I build correlation rules, dashboards, and automated alerts that reduce false positives and strengthen SOC operations. My work includes incident triage, log analysis, threat hunting, SIEM tuning, and collaborating with infrastructure and application teams to improve security posture.
