IT Infrastructure Professional | Network • Cloud • Security

7+ Years Network Operations | CompTIA Certified | Building Modern Infrastructure

IT Infrastructure professional with 7+ years at Charter Communications, building production-grade cloud and DevOps capabilities. Currently running a 5-service Docker homelab, publishing technical content across networking, cloud, and security domains, and demonstrating hands-on skills through real projects.

About Me

Born and raised in sunny Florida, I'm a '90s kid from the dial-up days - when getting online meant kicking everyone off the phone. Those early days of trying to get connected were some of my first lessons in IT and networking.

That early exposure to technology's transformative power sparked a lifelong passion. At the Center for Advanced Technologies at Lakewood High School, I learned the fundamental building blocks of coding and hardware - doing labs and learning computer systems. This foundation led me to St. Petersburg College, where I pursued an Associate of Science in Computer Programming, diving deeper into the logical structures that make our digital world function.

For the past 7+ years at Charter Communications (Spectrum), I've been providing technical support for internet and voice services, helping customers resolve connectivity issues, DNS problems, router configurations, and service outages. This customer-facing role has given me extensive exposure to network troubleshooting concepts and real-world infrastructure challenges.

High School: Center for Advanced Technologies → Coding/hardware fundamentals
College: SPC Computer Programming → Logical thinking & problem-solving
2017-Present: Charter Communications → Network operations & troubleshooting
2025: Docker Homelab → Production infrastructure & DevOps practices|

Currently, I'm building hands-on experience across multiple domains through practical projects. My Docker homelab running on Ubuntu Server is just the first - I'm documenting everything on my technical blog as I work through networking concepts, cloud technologies, and infrastructure automation.

The goal is simple: build real things, document the process, and demonstrate capabilities that translate to professional environments. Whether it's containerization, network design, cloud architecture, or security implementation - I learn by doing and share what works (and what doesn't).

Ready to bring 7+ years of network operations experience, proven infrastructure-building capabilities, and passion for modern IT to your organization.
