I monitor the network,
catch threats early.
I am a cybersecurity specialist working on network security, SIEM monitoring, and malware analysis. From firewall policies to incident analysis, CTF competitions, and end-to-end malware remediation, I operate on the defense side.
A defense-oriented perspective
I am a cybersecurity specialist with practical experience in network security, malware analysis, and security operations. I have designed firewall policies in enterprise-scale network environments and monitored infrastructure health and potential threats using SIEM solutions.
I led an end-to-end malware remediation process where I detected multiple backdoor families and unauthorized access points. I founded and scaled a digital agency providing WordPress security and maintenance.
I am an active CTF competitor, regularly working on crypto, web, forensic analysis, and reverse engineering categories. My focus is increasingly shifting towards Blue Team defense, incident analysis, and threat detection.
