About

Cybersecurity enthusiast with an Electronics & Telecommunication engineering background and hands-on experience in secure system operations, access control, and defensive security practices. I enjoy building and supporting systems that are not just functional, but secure by design—applying principles like Defense in Depth, Least Privilege, and Separation of Duties while keeping implementations practical and maintainable. In my current role, I handle end-to-end IT operations and service delivery—resolving ~52 ServiceNow tickets/month, supporting hardware/software/access issues within SLA, and contributing to a reported 60% performance improvement. I also manage backup operations and retention (with 99% backup accuracy), maintain audit-ready asset lifecycle control for 800+ devices with 100% CMDB alignment, and improve compliance through software reconciliation for 2,000+ applications (including removing 50+ unnecessary apps). On the security side, I’ve built practical projects such as a Secure Linux setup (RBAC for 8 users / 3 groups, ACL enforcement, auditd monitoring, automated reporting) and OpenVAS/GVM vulnerability assessments with exportable reports for remediation tracking. I’m now looking for opportunities in Cybersecurity Analyst / SOC / Security Operations / System Security roles where I can combine strong troubleshooting with a security-first mindset. Core strengths: Linux security • Access control (RBAC/ACL) • Vulnerability scanning (OpenVAS) • Audit logging (auditd) • ServiceNow • Asset & license compliance • Backup/retention • Troubleshooting • Reporting/Power BI • Stakeholder communication
