About Me

Professional Summary

I work where network security, systems administration, and cloud infrastructure meet.

I built my career through real infrastructure work, not only theory. Over the last 7+ years, I have worked in enterprise IT and ISP networking across network security, Linux and Windows server administration, mail systems, Active Directory, VoIP infrastructure, routing and switching, VPN operations, and cloud-connected production environments.

At the same time, I am finishing my Master of Science in Information Technology at Gannon University in Erie, Pennsylvania, with expected completion on May 9, 2026. As a Graduate Research Assistant under Dr. Kefei Wang, I have been using that work to push further into serverless security, Zero Trust architecture, AI-driven threat detection, and distributed cloud infrastructure protection.

Current Focus

Right now I am focused on network security engineering, systems administration, cloud infrastructure, and research that can turn into practical security tools.

Research Position

I am building my first-author research path around intelligent firewalls, federated threat intelligence, and Zero Trust automation, with published work and an active pipeline behind it.

Target Roles

The roles that fit me best are Network Security Engineer, Systems Administrator, Cloud Security Engineer, IT Infrastructure Engineer, and security-focused research or engineering roles.

Portfolio Projects

These are the projects I usually point people to when I want them to understand how I think. They sit around cloud infrastructure, network security, automation, data workflow design, and applied AI, and they show the ideas I cared enough about to build properly.

Infrastructure, Security, Automation, and Applied AI

I wanted these projects to show more than code. I wanted them to show how I think through problems.

I use these builds to show my thinking in serverless firewall design, Zero Trust security, threat intelligence integration, cloud-ready automation, data analysis tooling, and multi-agent AI systems. For me, they are one of the clearest ways to connect my engineering work with the research direction behind it.

Knowledge Sharing

Blog and Insights

I use this part of my site to explain my work in a more personal and readable way. A resume or a short portfolio card can only say so much, so here I write about my industry experience, client work, GitHub projects, and research in a way that feels closer to how I would explain it in a real conversation.

Why I Write Here

I wanted one place where I could talk about my work in my own words.

On the homepage, I keep things short. In the blog, I slow down and explain what I built, what I learned, what problems I was trying to solve, and why the work matters. I write about network security, Linux and Windows systems administration, cloud infrastructure, client delivery work, applied AI projects, and research that grew from the same real interests.

For Hiring Teams

If you are hiring, this part shows how I think through network security, systems work, cloud infrastructure, and research-led engineering in a more complete way than a resume can.

For Clients

If you are thinking about working with me, these notes give you a clearer picture of the kind of service work I have done across mail, file, web, telephony, network design, and cloud systems.

For Research Review

If you want to understand my research without reading a paper first, I explain my published work, current submissions, and first-author ideas in simpler language here.
