What I'm looking for

I’m seeking a challenging position where I can apply my experience to accomplish tasks, build and motivate teams, and execute accurate solutions.

At R1 RCM Philippines Inc., I develop incident response playbooks and automate response actions. I monitor SIEM, XDR, system logs, and alerts, and investigate incidents to assess their impact and severity.

Previously, at EY GDS (CS) Philippines, Inc., I worked as an L2 SOC Analyst / EDR Engineer, deploying and managing endpoint detection and response solutions and tuning policies. I also investigated verified incidents and documented findings and remediation recommendations.

At Crown Worldwide Global Business Services Inc. | Philippines and St. Luke’s Medical Center, I worked on security monitoring and incident response using SIEM tools. Earlier roles at Adventus IT Services Philippines and Fresenius Medical Care Philippines, Inc. covered IT administration, infrastructure, network support, and PHP web development.
