What I'm looking for

I’m available for remote roles across the EU or on-site in Tallinn, and I don’t require visa sponsorship.

At Tallinn University of Technology, I monitor alerts and network traffic with the Elastic Stack (Kibana) and NfSen. I investigate daily alerts, document my findings, and prepare and present a weekly report to the team.

In my cybersecurity projects, I built a PowerShell toolkit for Windows security tasks and a Wazuh SIEM lab to test and tune detections against MITRE ATT&CK techniques. I’m studying for an MSc in Cybersecurity at Tallinn University of Technology, building on hands-on work in security monitoring, IT support, and software engineering.
