What I'm looking for

I'm looking to strengthen enterprise and cloud security through Zero Trust, SIEM monitoring, threat detection, incident response, and security automation while contributing to compliance-focused security programs.

At Zscaler, I engineer Zero Trust Network Access policies, secure web gateway controls, and CASB/DLP policies to protect enterprise applications, SaaS data, and distributed cloud environments.

I've automated security log ingestion and investigation workflows with Python and PowerShell, integrated Okta with Zscaler for SSO, MFA, and conditional access, and used AlienVault OTX and ThreatConnect to strengthen proactive threat detection.

Previously at Palo Alto Networks, I monitored enterprise threats with Cortex XDR and Splunk, reduced incident escalation times by 32% through threat hunting, and reduced triage workloads by 30% with Cortex XSOAR playbooks. I also performed VAPT, malware analysis, SIEM investigations, and packet-level network analysis while supporting NIST and PCI DSS compliance.
