What I'm looking for
At It4us Cyber Security, I triaged and investigated over 100 monthly offenses in IBM QRadar SIEM, classified events, and escalated critical incidents in a multiclient operation. I also mapped TTPs to MITRE ATT&CK and documented evidence while tracking Jira tickets and SLAs.
My Cyber Threat Intelligence work involved using Axur to investigate possible credential exposures, phishing, suspicious domains, and brand abuse, including analyzing false positives and communicating mitigation recommendations. In personal projects, I built a SOC lab with Elastic Stack and Sysmon, detection rules and simulated incident reports, as well as a log analyzer in Python.
