🚀 About Me

I am an Infrastructure Security Engineer and Edge Infrastructure Architect with a focus on building zero-trust, self-hosted digital ecosystems. My philosophy is simple: your data, your hardware, your rules. I design and operate private infrastructure that runs entirely on edge hardware with no third-party dependencies.

• 🏗️ Infrastructure Architect: Building resilient, self-hosted systems on Raspberry Pi clusters and edge devices.
• 🔐 Security Engineer: Implementing Zero-Trust Architecture, Tor networks, and robust firewall configurations.
• 🌐 Open Source Advocate: Contributing to the community through tools, documentation, and guides.
• 🐧 Linux & Container Specialist: Expert in Debian administration and Docker orchestration.
