I am a cybersecurity professional based in the Czech Republic, currently working as a Senior Security Specialist and Malware & Vulnerability Protection Tech Leader at Česká spořitelna.

My native language is Czech. I am professionally proficient in English at a B2 level and have a basic understanding of Russian at an A2 level.

My primary professional focus is on vulnerability management, malware protection, and security controls in large enterprise environments. I work mainly with technologies such as Qualys VMDR, Tenable Vulnerability Management, Check Point Next Generation Firewall, and Archer GRC. On the server level, I administer both Linux and Windows environments. For daily desktop use, I prefer macOS or Debian-based Linux distributions.
