Skobioale
Third-year IT student based in Tartu, Estonia. Building reliable, secure infrastructure and learning how systems fail. Hands-on experience across networking, virtualization, identity management, offensive security, and cyber defence competitions — including Locked Shields 2026 (NATO CCDCOE).
Summary
During my internship at Prakti.net I designed and deployed a full on-premise environment from scratch — network architecture, 3-node Proxmox HA cluster, Active Directory with dual DC, VLANs, Keycloak SSO, internal services, and Zabbix monitoring. At cybertech.global I conduct security research, build simple CTF challenges, and ran an authorized phishing simulation with full mail infrastructure (GoPhish, Postfix, DKIM/SPF/DMARC). I compete in national and international cyber defence exercises and am working toward CompTIA A+, Network+, and Security+. Considering a Bachelor's in Cybersecurity Technologies as the next step in my career and am highly motivated to continue developing practical skills, gaining hands-on experience, and contributing to building secure and resilient systems in professional environments.
Experience
- Security research focused on red teaming methodologies and offensive security techniques.
- Designing and building simple CTF challenges covering OSINT, web security, cryptography, and exploitation.
- Producing technical educational video content for the CYBERTECH training platform.
- Ran an authorized phishing simulation: GoPhish + Postfix with DKIM/SPF/DMARC on VPS; analysed results.
- Designed full network architecture: VLAN segmentation, trunking, IP addressing, DNS and DHCP.
- Deployed a 3-node Proxmox VE high-availability cluster with RAID 1 and Synology NAS shared storage.
- Built Active Directory with dual DC replication, OU structure, security groups, and group policies.
- Implemented Keycloak SSO integrated with AD; configured RADIUS for Wi-Fi and VPN.
- Deployed internal services: Nextcloud, OpenProject, Vaultwarden, Pi-hole + Quad9.
- Monitoring with Zabbix and Uptime Kuma; managed SSL/TLS certificates and reverse proxies.
- Produced SOP documentation, network topology diagrams, and security hardening guides.
