What I'm looking for

I seek a role where I can lead incident response and cloud security efforts, contribute to compliance programs, automate detections, and grow into senior security responsibilities within a collaborative team.

I am a cybersecurity analyst with 4+ years securing enterprise systems in payment processing and financial services, focused on reducing incidents and maintaining PCI DSS and SOC 2 compliance.

I have hands-on experience with SIEM platforms (Splunk, Azure Sentinel), cloud security (AWS, Azure), vulnerability management (Nessus), and endpoint protection, and I have led incident response and audit readiness initiatives that delivered measurable reductions in incidents and improved controls.

I build automated detection and remediation workflows using PowerShell, Python, and KQL, develop clear security documentation, and partner across teams to implement least-privilege access, encryption, and process improvements that strengthen security posture while minimizing business disruption.
