Welcome to my GitHub 👋
I’m a cybersecurity-focused IT professional building and documenting realistic, enterprise-style security labs. My work emphasizes network foundations, security analysis, structured adversarial testing, and evidence-based documentation aligned with real-world security operations.

I focus on how systems are designed, tested, and defended—not just which tools are used.

🔍 Security Research & Testing
Network discovery, service enumeration, attack surface analysis, and remediation-focused documentation.

🛡️ Cybersecurity & Risk Analysis
Adversarial thinking, defensive validation, and secure system design with operational context.

☁️ Cloud & Enterprise Technology
Experience across cloud platforms, access control models, and modern IT environments.

🧪 Hands-On Technical Work
Isolated labs, tooling evaluation, and disciplined evidence handling with clear technical communication.

Enterprise-style security lab simulating real-world network segmentation, discovery, testing, and defensive workflows.

• Firewall deployment and WAN/LAN segmentation (pfSense)
• Network discovery and enumeration
• Vulnerability assessment foundations
• Structured lab documentation with validation evidence

Structured security testing projects focused on:

• Scoped network discovery and service enumeration
• Adversarial risk analysis
• Sanitized evidence and professional reporting
• Tooling limitations and lessons learned

• Master of Information Systems Management — Completed
• Master’s Degree in Cybersecurity & Information Assurance — In Progress
• DeVry University — Alumnus

• Network Security & Vulnerability Assessment
• Security Testing & Research Methodologies
• Nmap, Burp Suite, OpenVAS / Greenbone
• Risk Assessment & Technical Documentation

• Web Application Analysis
• Git, Linux, and Virtualized Lab Environments

This GitHub reflects my progression from general IT and development work into focused security engineering and security research. Emphasis is placed on process, judgment, and communication—not tool output alone.

Repositories are documented to be explainable, defensible, and aligned with professional security workflows.

I enjoy collaborating with others interested in:

• Security research & testing
• Enterprise risk reduction
• Continuous learning and technical growth
