💼 Career transition: CNC Programmer → IT/Cybersecurity
This repository documents my hands-on learning journey building and securing real infrastructure. Everything here runs on actual hardware and reflects real decisions
💡 Repository Purpose
What this is:
- Working documentation for my production homelab
- Portfolio of applied security concepts
- Learning journal with real implementations
Current infrastructure:
- Debian 12 server (server-lf1) running Pi-hole + N8N
- Raspberry Pi NAS with PhotoPrism + Samba
- Raspberry Pi syslog sensor (Blue Team practice)
- Flipper Zero security testing
- Self-hosted AI models (Ollama, Stable Diffusion)
Goals:
- Apply classroom concepts to real systems
- Build maintainable, documented infrastructure
- Create technical portfolio for career transition What this is:
