I'm a hands-on system administrator and networking enthusiast building expertise in infrastructure security and operations. My work spans from low-level systems programming to production-grade deployments, with a strong focus on understanding how systems work under the hood.
Current Focus:
├── Infrastructure & Virtualization (Proxmox homelab)
├── Network Security & Protocol Analysis
├── Systems Programming (C, Java, Rust)
└── Security Research & Penetration Testing
- OS Administration: Linux (Debian, Ubuntu, Fedora, RHEL, Arch), Windows Server (Active Directory)
- Virtualization & Containerization: Proxmox VE, VMware, VirtualBox, Docker (learning Kubernetes)
- Services & Tools: Nextcloud, Apache, PostgreSQL, MySQL, pfSense, OpenVPN, DNS/DHCP
- Protocols & Concepts: TCP/IP, routing, switching, firewall configuration, IDS/IPS, OWASP Top 10
- Tools: Wireshark, Nmap, tcpdump, Burp Suite, Nessus
- VPN & Firewall: pfSense, OpenVPN
- Languages: C, C++, Java, C#, Python, JavaScript/TypeScript, Bash
- Backend: .NET Core, Spring Boot, Node.js/Express
- Frontend: React, Next.js
- Version Control & CI/CD: Git, GitHub Workflows
- zmix – Tor-inspired P2P anonymous network with layered encryption
- zetra – Educational blockchain exploring consensus and cryptography
- ztron – Merkle tree builder and verifier for file integrity (work in progress)
- socket-msg-exch – Raw TCP socket message exchange in C
- lzw-compression – Classic LZW compression algorithm in Java
- zordo – An AI-assisted task scheduling and planning engine for students
- library-management-system – Full-stack CRUD app for managing books and authors
- portfolio – Self-hosted personal site for showcasing projects and experience
- campus-companion – AI-powered student tool platform focused on community engagement
Fun fact: You can't get hacked if you pull the cable in time... right? 🤓🔌💥"
Current Setup:
- Hypervisor: Proxmox VE cluster managing multiple VMs
- Services: Apache, Nextcloud, PostgreSQL/MySQL, dev environments
- Network & Security: VLAN segmentation, pfSense firewall, VPN, regular patching
Learning Goals
**Learning Goals:** - Infrastructure as Code with Ansible - Docker Swarm/Kubernetes orchestration - Centralized logging (ELK stack) - Web & Network Security: OWASP Top 10, IDS/IPS, penetration testing - Tools: Burp Suite, Metasploit, Nessus - Certifications: CompTIA Security+, CEH, CCNA
