Blue and purple team security engineer based in Kaunas, Lithuania. SEC1 certified. I build defensive infrastructure, write detections, and document the work in public.
Selected projects from my local GitLab forge:
- NoxLab: reference architecture for a self-hosted security homelab on one box. Segmented network, tiered Docker, self-hosted GitLab CI/CD, SIEM with local-LLM triage, tested bare-metal DR.
- tripwire-honeypot: deception-based intrusion detection using a fake sudo group as a canary. PAM hooks, Wazuh integration, MITRE ATT&CK and D3FEND mapping, Terraform deployment.
- nethunter-s10e-fix: kernel and Magisk modules restoring missing HID functionality in Kali NetHunter on the Galaxy S10e. Hardware and firmware-level Linux work.
- msi-power-profile: power profile suite for MSI laptops on Linux, layered on top of TLP.
Home SOC built in under six months on Wazuh, processing 160,000+ events per day, with rule refinement and OpenSearch dashboards. Detection engineering, deception, and incident workflow automation. Security+ exam prep.
