About
Army background with practical engineering experience — I build reliable systems and learn fast.
Currently studying CS at MTSU with a cybersecurity focus.
My Story
Military Foundation
Four years as an Army IT Specialist taught me that reliable systems aren't built by chance. I managed classified networks across two continents, handled $750K in critical infrastructure, and learned that security isn't just a feature—it's the foundation everything else relies on.
Academic Foundation
Completed Associate of Science in Computer Science at Nashville State Community College (Jan 2022 - May 2024). Currently pursuing Bachelor's in Computer Science with cybersecurity concentration at MTSU. Military discipline translates directly to systematic debugging, secure coding practices, and deadline-driven development cycles.
How I Debug
I debug like I troubleshoot Army networks - systematically, coffee-fueled, until it works. Break it down, Google the weird error, try stuff until something clicks. Usually works around 2am with enough caffeine.
Beyond Code
Behind the bar at Nashville's biggest venues, I've learned to read people, handle pressure, and deliver under chaos. FSU Seminoles bleed through my veins on Saturdays. Live music feeds the soul, good food fuels the grind, and art keeps the mind creative. Family anchors everything - they're my why for all the late nights coding and studying.

Featured Projects
Here are some recent projects that showcase my technical skills and problem-solving approach.
Featured Work
🚦 TrafficWiz
Built this for an MTSU Database Management Capstone project - Nashville traffic data meets ML. Predicts traffic better than existing city dashboards and navigation apps.
🔒 Safe URL Checker
Checks if URLs are sketchy or not. I made this tool after falling for one too many 'you won a free iPhone' links. Works surprisingly well.
Chat-Room MTSU
C++ chat app using TCP Sockets. Two people can talk to each other across different devices. Revolutionary stuff lol. I actually got it working from my iPad to PC using SSH, which felt pretty good.
PantryMate
PantryMate — AI-powered food inventory tracker that helps people see what's in their pantry, plan meals, and reduce food waste.
Other Projects
🔐 Network Security Tools
Collection of networking and security tools including socket programming, SSH configurations, Wireshark analysis, Nmap scanning, and port proxying implementations.
📊 Data & ML Integration
Python backends with traffic prediction models and dashboard visualization. Includes data analysis, machine learning model integration, and real-time data processing.
🌐 Portfolio Website
This very portfolio website showcasing responsive design, smooth animations, and modern web practices. Built with Next.js, TypeScript, and Tailwind CSS.
⚙️ System Administration
Advanced systems work including WSL2 configurations, PowerShell scripting, Bash automation, and cross-platform development environments.
