Junior IT Infrastructure & DevSecOps Enthusiast

First-year BSc Digital Systems student at the University of Piraeus. I am an adept problem-solver passionate about secure network architectures, homelabbing and OS administration. I build robust infrastructures out of resource-constrained environments as learning opportunities.

• Zero-Trust Infrastructure: Managing a hybrid bare-metal Arch Linux homelab. Orchestrating 10+ containers (Docker) including Nginx Proxy Manager, Vaultwarden and Uptime Kuma, with all external traffic secured through a strict WireGuard VPN tunnel.
• Network Privacy & Routing: Architecting encrypted DNS pipelines using Pi-hole integrated with dnsproxy (DNS-over-HTTPS via Quad9). Configured router-level port forwarding. Set strict UFW default-drop policies and explicit UFW route rules for VPN micro-segmentation.
• Hardware Modifications & Firmware: Successfully bypassed OEM hardware write-protections on Chromebook motherboards. Deploying standalone Linux environments on repurposed hardware as a server.
• Alternative Compute Environments: Exploring varied compute architectures beyond standard Desktop OS, including Oracle VirtualBox, Kali Nethunter on mobile, and ChromeOS developer environments (Crostini terminal/LXC and Crouton chroots).
• Database & Chaos Engineering: Architected and used MS SQL Server environments to learn T-SQL. Simulated data destruction to practice execution plan optimization and execute precise RESTORE DATABASE ... WITH NORECOVERY operations.

• OS & Administration: Windows, ChromeOS (Crostini LXC & Crouton chroot), Mobile Linux (Termux, Kali Nethunter: GUI via VNC) and Linux Distributions (CLI & GUI: Arch, Ubuntu, Kali, Mint).
• Networking & Security: TCP/IP, WireGuard, Nginx Proxy Manager, UFW / iptables, Pi-hole, dnsproxy (DoH), Nmap, Wireshark.
• Virtualization & Containers: Docker & Docker Compose, Oracle VirtualBox, Mobile Linux (Termux).
• Scripting & Observability: Bash/Shell, Python, C, Git Version Control.
