What I'm looking for

I'm open to remote security engagements and have been working in distributed international teams since 2021.

At TelkomSigma, I investigate enterprise security incidents using Splunk to correlate network, endpoint, and application logs. I reconstruct incident timelines, scope impact, and prepare forensic reports with remediation recommendations for SOC teams, stakeholders, and legal proceedings.

My years in ISP network operations shape how I approach incident response: I validate suspicious traffic against network activity and SIEM data. At Connexin, I supported backbone operations for a UK-based ISP, investigating routing issues involving BGP, OSPF, MPLS, and VPLS; I also deliver MikroTik certification training through ID-Networkers.
