About Me

I am completing a Bachelor of Science in Information Technology with a concentration in Systems Administration and Cybersecurity, graduating May 2026. I design secure lab environments, deploy and manage Active Directory domains in Azure, conduct structured digital forensic investigations, and build Android applications using secure architecture principles. I focus on building, documenting, and securing real-world technical environments.

Core Technical Focus

  • Active Directory and Azure domain deployment
  • Network security lab design and vulnerability analysis
  • Digital forensics workflows and evidence validation
  • Secure Android application development using MVVM architecture

Featured Projects

VirtualBox Penetration Testing Lab

Controlled lab environment simulating real-world vulnerability assessment using Kali Linux and Metasploitable.

Azure Active Directory Domain Deployment

Enterprise-style Windows Server domain build with OU structure, Group Policy configuration, and identity management.

Digital Forensics Investigation Lab

Forensic imaging, hash verification, file signature analysis, and tool validation aligned with industry standards.

Senior Connect Android Application

Mobile application built with Kotlin, Room database, and structured architecture focused on usability and safety.
