Fiber Optics 95%Born in 1987 in New Jersey, I embarked on my journey into the realm of technology as an aspiring developer and Cyber Security Analyst. My fascination with technology was ignited at the tender age of 10, following my first encounter with a personal computer. This early experience sparked a relentless curiosity about the inner workings of computers and set the stage for my future career path. While my jobe wasn't tech related, my service in the Army helped me find who I wanted to be and proved to be a transformative period, deepening my passion for technology and steering me towards specialized fields within the tech industry. It was during this time that I developed a keen interest in Web Development, Networking, Coaxial and Fiber Optics, Network Security, Software Development and Analysis, and, ultimately, Cyber Security. This diverse expertise has not only enriched my understanding of the digital world but also equipped me with a comprehensive skill set that I continue to expand in my professional endeavors.
I am passionate about technology and often work on multiple projects simultaneously. When I encounter an issue, I assess it and prioritize accordingly. I am currently working towards my Master's Degree in IT Security.
In my free time, I enjoy listening to music, spending time with my wife and children, working on random tech projects, being outdoors, and taking care of my homestead.
In addition to my technical pursuits, I have authored two publications. The first book delves into the intricacies of Fiber Optics, offering a comprehensive exploration of its principles and applications.
The second book focuses on Linux, specifically its command-line interface, and includes practical cheat sheets to enhance user proficiency and efficiency. These works reflect my commitment to sharing knowledge and contributing to the broader tech community.

Here is an overview of the services & products I currently run/provide
I host my own cloud service, allowing family and friends to store their files, manage their schedules using CalDAV add-ons, and create and edit spreadsheets, presentations, and other documents. The cloud is my most worked-on project to date. Keeping up with security, users, hardware, and unpredictable internet can turn into a daunting task.
I have been running a media server for the same group of people who use my cloud service for quite a few years now. This is something I enjoy—being able to stream my own lossless audio and movies anywhere, rather than pay for services, is an amazing feat to me.
A DNS server is vital for resolving easy-to-remember URLs into the actual IP addresses that servers listen to, like 9.9.9.9, for example. Running one on your own is no easy task. Nevertheless, I took on the challenge myself, and it's working very well, resolving roughly 15 million requests every day, using my own upstream and recursive resolver.
Hacking, specifically malware and unauthorized access, has always fascinated me. This interest dovetails nicely with my existing network knowledge and software development skills.
I enjoy starting projects that I find fun; this approach helps keep me engaged and continually learning. My interests aren't confined to a specific area of technology. Recently, I've been assembling new boards for my Flipper Zero and working on developing a customizable service-level application. This app will allow users to display any data they choose in a widget, or across multiple devices, on a Raspberry Pi 4 (or newer models).
