Message

At Nordic Defender AB, I own security and infrastructure delivery across four AWS environments for a cybersecurity SaaS platform. I built and tuned Wazuh SIEM with custom decoders and detection rules, cutting false positives and mean-time-to-detect by 60%.

At FASP Co., I redesigned Tejarat Bank's internet banking security architecture using three-tier isolation across Juniper SRX, Cisco Firepower, FortiGate, FortiWeb, and FortiAnalyzer. Across my work, I’ve delivered network security for SaaS, banking, and industrial environments, including two consecutive SOC 2 Type II audits with zero major findings.
