At GCS we strive to surpass our clients needs while implementing the latest technology to support and help grow their business.


My interest in IT began when Internet and Technology took off as I grew up in the Late 90’s.  I can still hear the wonderful, melodic tune of the 56K modem dialing up to connect me to this new, vast world.


After High School, I enlisted in the military and served 4 years in the United States Navy as a Operations Specialist.  This was an amazing experience for me as I was able to travel the world, meet tons of different people and work in high-pressure, critical environments.  This experience taught me a lot about Technology, people, the world and helped shape my core values of hard work and integrity.


After the Navy, I attended Stony Brook University and graduated with a Bachelors Degree. I quickly then began my professional civilian career as a Junior Technician, working my way to my current IT Management position here at Global.

Matthew Zegilla

VP of Engineering


I am going on eight years of experience working in IT and hold a A.A.S in Network Design and Administration from Suny Suffolk. I worked from an Intern Helpdesk position at a different company to my current senior position here at Global, my wide range of expertise from experiencing all levels of support help me diagnose issues quickly and accurately. Working directly with the leadership team of Global has also helped me to understand the business side of our clients to help identify solutions that work both technically and practically with our clients budget, schedule, and business needs. Due to this experience I have been able to help many of our clients with projects involving thousands of devices and hundreds of users get completed in a timely, cost effective, and technically sound manner.


I have experience with a wide range of technologies including cloud offerings such as Microsoft Office 365 Exchange Online, Microsoft Azure Active Directory, Microsoft Azure Compute and Blob Storage, as well as on-premise tech such as VMWare 6.7, IBM Storwize SAN, HP Proliant server hardware, Windows Server 2019, Microsoft Exchange 2019, Veeam Backup and Replication, HP and Cisco networking, Fortinet and Cisco security appliances, as well as many other hardware and software vendors.

Outside of work I am an avid PC gamer and enjoy spending my time with my girlfriend and our dog.

I manage and monitor the infrastructure of multiple clients. I also configure, test and maintain a wide variety of technical components at our clients locations. I can be described as an ambitious responsible person looking to gain as much knowledge in the field as possible. I have studied a variety of different technologies with the mindset that an all around skillset will prove to be useful in any given situation.


I am proud of a couple of goals I have achieved whilst in this profession. I have implemented a vmware view environment into a clients infrastructure while learning about the product. I have also helped restore a company after a serious ransomware attack while still keeping them productive. I am most proud of my ability to learn new products and implement them.


With a double VCP certification I am proficient with VMware products. I however also have knowledge in vast areas. Some but not including all are Active Directory and Windows server infrastructures, veeam backup, IBM Storwize, HP Proliant and Lenovo System X servers etc. As a previous depot technician for Estee Lauder I also have a lot of hands on hardware experience.


I am a single father with a nine year old daughter. I am a provider and take my career seriously. I feel as though my personal life will be directly effected by my career. So I study often. When I am not studying, I spend quality time with my daughter. I love watching anime and going on adventures with my daughter.

My name is Nick Cerafice, and I’m a Support Engineer for Global Computer Systems. I started here almost 2 years ago, and I can’t believe how fast the time has gone by! I’ve learned a lot of new things – and although I still have a lot to learn - I was very much so a rookie when I was first on-boarded.


I have my Bachelors in CIT, and come from a childhood filled with technology. Whether it was game consoles, desktop computers or cell phones, I was exposed to technology at a very early age. This background helped fuel my interest in technology, and some of the knowledge I’ve gained working on computers in my personal time is still useful to me on a daily basis at work.


Most desktops/laptops I’ve owned are Asus & Acer Brand. They’ve been very reliable to me, and run just about as well as they did when I first got them. I recommend them to most people who ask me personally what I like. I’ve also always leaned towards Samsung phones more-so than Apple, but I’ve owned a few Apple devices as well.


Outside of work, I work with Excel & Google Sheets quite a bit, as I’m constantly noting stuff I need to remember for my hobbies. I like to speedrun video games, which means to complete them as fast as possible while still meeting the requirements as to what clarifies as “completed” to the community. There are different categories for each game, such as 100% completion, and just finishing the game as fast as possible – “Any%”.


Speed-running often requires quick, on-the-spot thinking and decisiveness to be successful. We’re always updating our sheet of notes on what we need to do, re-routing the best way to finish the game the fastest, and brainstorming with each other on what we can add/subtract from the route. I believe these regularly used skills assist me greatly on the job, and I couldn’t be happier about this hobby I’ve picked up.
