PROFESSIONAL SUMMARY:

With over 14 years of IT experience, including 12+ years dedicated to ServiceNow, I specialize in architecting and implementing enterprise-grade solutions across ITSM, ITOM, ITAM, ITBM, HRSD, SecOps, GRC, and CSM modules. I have led end-to-end implementations, integrating ServiceNow with AWS, Azure, and on-prem systems using Cloud Management and IntegrationHub. My expertise includes AI-powered automation through Now Assist, Predictive Intelligence, Virtual Agent, and Flow Designer, enabling smarter workflows and proactive service delivery.

In addition, I bring deep hands-on experience in Security Operations (SecOps) and Application Vulnerability Response (AVR), including the integration of Invicti (Netsparker) with ServiceNow to automate vulnerability correlation and remediation workflows. Skilled in JavaScript, Glide scripting, and REST integrations, I design scalable automation and security solutions that enhance visibility, accuracy, and compliance across enterprise environments. Passionate about driving digital transformation, I ensure every ServiceNow deployment aligns with organizational goals and maximizes operational efficiency.
