Technology & Infrastructure Solutions

CompTIA A+ certified professional with a background built on New York City's streets — literally. What started at age four as a street vending career became a graduate-level education in customer instinct, pressure management, and the art of closing. Today that foundation supports enterprise access control operations at a major NYC university, solo-built institutional software, and a growing portfolio of technology and business solutions for clients who expect the work to speak for itself.

About

Background & Trajectory

I began my career at age four, working alongside family as a street vendor in New York City. From elementary school through the end of high school, the sidewalks of this city were my first professional environment — where I developed customer service instincts, composure under pressure, and the ability to communicate effectively with every kind of person, long before I had a technical credential to my name.

Today I operate enterprise access control systems at Hunter College's Visitor Center — one of New York City's premier public universities — providing direct support to over 200 visitors daily, including VIP guests and the President's Office. I hold a B.S. in Computer Science from Hunter College and CompTIA A+, with Security+ in progress.

My work spans IT infrastructure, workflow automation, and digital solutions — built for organizations that operate at a high standard and need technology that keeps up. I'm available for consulting engagements, project work, and select full-time roles in technology and IT.

I'm guided by the conviction that work is a privilege, not a given — and that anything worth doing is worth doing at the highest level possible. That standard is non-negotiable regardless of the task at hand.
