What I'm looking for

I am looking for a role that challenges my skills in cybersecurity and allows for professional growth within a collaborative and innovative environment.

I am a cybersecurity expert with over a decade of experience in security operations, SIEM solutions, threat analysis, and cloud security. My strong technical background in scripting, network security, and security architecture has enabled me to enhance security postures and build SOC capabilities for enterprise clients across the APAC region.

Throughout my career, I have held various roles, including Technical Account Manager at Fastly Inc., where I assist customers in achieving their strategic security objectives. I have also led SIEM implementations at DXC Technology Japan, improving security visibility and response. My key achievements include developing SIEM use cases that improved detection accuracy by 40% and automating threat detection processes, significantly reducing manual analysis time.
