What I'm looking for

I am looking for a role that challenges my skills in cybersecurity and offers opportunities for professional growth within a collaborative team.

I am a motivated and detail-oriented Security Analyst with a strong background in ICT. With over three years of experience in security monitoring, incident response, and vulnerability management, I have developed a keen ability to identify and mitigate threats in enterprise environments. My expertise includes working with SIEM solutions such as McAfee ESM, Splunk, and Microsoft Sentinel, which has equipped me with the skills necessary to analyze security events and respond effectively to incidents.

Throughout my career, I have demonstrated strong analytical skills and a proactive approach to security challenges. In my current role at Globallogic/Hitachi Cyber, I monitor and analyze security events, conduct in-depth log analysis, and support incident response efforts across diverse environments. I am committed to continuous improvement and have contributed to enhancing the performance of security tools to strengthen organizational security posture.
