Building systems that
protect and connect

I'm pursuing a Bachelor of Science in Security Systems at Farmingdale State College (graduating May 2027), concentrating in Networking. My work spans building automation, cybersecurity, and critical infrastructure — grounded by three years of hands-on experience at Siemens Smart Buildings.

Outside of tech, I serve my community as a Volunteer Firefighter and EMT with the Middle Island Fire Department — EMT of the Year (2026), Probationary Firefighter of the Year (2023).

Eagle Scout. Cisco networking student. Splunk analyst. I thrive at the intersection of physical systems, digital infrastructure, and community service.
