What I'm looking for

I’m looking for a cyber-security role where I can expand my SOC and threat-hunting work, strengthen vulnerability and risk management, and improve monitoring and incident handling—while growing through continuous training in a security-focused team.

I’m a Cyber Security Specialist with proven expertise in threat assessment, vulnerability management, incident response, and building security policies that support compliance. I’m committed to continuous learning and staying current with cyber-security trends and technologies.

In my current role at NM B BANK LTD (DECEMBER 2021 — PRESENT), I lead penetration testing across servers and perform threat hunting, modelling, and analysis. I manage SIEM, monitor security logs, support incident handling, and strengthen defenses through firewall management, firewall policy reviews, and Anti-Virus management.

I also manage privileged and endpoint security controls—handling PAM, Duo administration, and Mobile Device Management—while working with XDR/NDR/EDR environments for risk assessment and vulnerability assessment. Previously, I served as a SOC reporting and Security Operations Center Analyst and as a Junior Specialist focused on Active Directory, Azure administration, backup monitoring, SolarWinds administration, SOPHOS firewall management, and user support.
