person About me

I’m a final-year Cyber Security Engineering student at TalTech and currently working as a Junior Cybersecurity Engineer in Tallinn.

My hands-on experience includes incident investigation and remediation (Cortex XDR), identity and access management, and building SIEM/XDR solutions with Wazuh + custom YARA rules.

I also have practical software development experience (PHP/JavaScript/Python) and enjoy automation workflows with n8n and LLM integrations.
