I'm building and operating SIEM capabilities for Indonesia's financial, capital markets, transportation, and regulatory environments. At PT Mitra Integrasi Informatika, I monitor security events, investigate threats, tune detections, and coordinate incident response across Splunk ES, Microsoft Sentinel, and Wazuh.
For a financial regulatory authority, I developed custom detection rules, SOAR playbooks, and compliance dashboards while administering a three-node Splunk Search Head Cluster. I've resolved P1 incidents involving indexer disk saturation, Data Model Acceleration resource consumption, scheduler collapse, and cluster configuration issues.
For a capital markets institution, I implemented Microsoft Sentinel end-to-end, integrated multi-vendor security logs, and developed KQL analytics rules and automated response playbooks. I have also delivered threat hunting, UBA implementation, agent onboarding, and log analysis for a national transportation operator.
I'm certified in CEH v12, CSA, CND v2, ECIH v2, CompTIA Security+, and Fortinet Certified Fundamentals, with a focus on practical detection engineering and resilient security operations.
