What I'm looking for

I’m looking to contribute long-term value to a global organization with a strong security culture.

At Lotte Finance, I deployed BeyondTrust PAM and wrote 50+ custom applications to manage privileged access for more than 500 systems. I also built Trellix DLP across 2,000+ devices and a local AI model that detects malware with more than 95% accuracy.

Previously, I operated security platforms at Techcombank and Homecredit, covering endpoint security, privileged access, cloud security, and incident response. At MI2JSC, I implemented enterprise security solutions, including SIEM, endpoint protection, and firewalls.
