🛠️ IT Support Technician | Cybersecurity Enthusiast
🔐 Transitioning into Cybersecurity through hands-on home lab projects

I am an IT Support Technician with a strong interest in cybersecurity, Linux infrastructure, and network security.
I am especially passionate about open-source applications, preferring transparent, community-driven tools that enable deep learning through real-world implementation and customization.

I actively build and manage home lab environments using open-source technologies to gain practical experience in secure system design, monitoring, and automation.

• IT Support → Cybersecurity
• Home lab–driven learning
• Practical infrastructure & security projects
• Automation-first mindset
• Open-source–centric approach

• 🖥️ Proxmox Virtualization (VMs & Containers)
• 🐳 Docker & Docker Compose
• 🔐 Network Segmentation (VLANs)
• 🌐 VPN Setup & Secure Remote Access
• 🚫 DNS Filtering (Pi-hole, AdGuard Home)
• 🔁 Reverse Proxy & HTTPS
• 🛡️ Linux Server Hardening
• 📊 Monitoring & Logging
• ⚙️ Automation with Bash & Python
• 🧪 Cybersecurity Home Lab (Controlled Environment)

🖥️ Tech: Proxmox, Linux, VLANs, Firewall
📌 Description:
A virtualized home lab designed for cybersecurity learning and infrastructure testing.

I strongly believe in the power of open-source software for learning, security, and innovation.

Why open-source?

• 🔍 Transparency and trust
• 🌍 Community-driven improvements
• 🧠 Deep learning through customization
• 🔐 Security through visibility, not obscurity

Most of my projects are built using open-source tools and platforms, and I enjoy contributing through documentation, testing, and sharing reproducible setups.

I believe clear documentation and open knowledge sharing are just as important as working systems.

Each project includes:

• 📄 Clear README with architecture overview
• 🛠️ Step-by-step setup instructions
• 🔐 Security considerations
• 🧠 What I learned & future improvements

All documentation is written with the mindset of open-source collaboration and reproducibility.

• Virtualization: Proxmox
• OS: Linux (Ubuntu, Debian)
• Containers: Docker
• Networking: VLANs, VPN, DNS, Firewalls
• Security: Hardening, DNS filtering, HTTPS
• Monitoring: Grafana, Prometheus
• Automation: Bash, Python
• Version Control: Git & GitHub

• Strengthen cybersecurity fundamentals
• Build realistic attack/defense lab scenarios
• Improve Linux & networking depth
• Automate infrastructure tasks
• Prepare for entry-level cybersecurity roles
