I believe that effective security isn\'t just about tools; it\'s about streamlining operations with playbooks, baselines, and dashboards that track control effectiveness in real-time.My core expertise includes:* Security Architecture: Shaping cloud security by enhancing AWS and Azure controls, monitoring, and compliance frameworks.* Threat Management: Staying ahead of threats through proactive vulnerability management, detection, and incident response using SIEM/XDR solutions.Strategic Collaboration: collaborating across IT, Cloud, SOC, and Risk teams to embed secure practices into the organization\'s DNA.Project Delivery: Delivering hands-on security projects from risk assessments to control uplift and automation.I am passionate about bridging the gap between technical security controls and business objectives, ensuring scalability and resilience against evolving cyber threats.
