The kind of engineer who thrives on what others call impossible. MBTA rail shutdowns on tight overnight windows. A 1935 stone church converted into a mixed-use asset. I build at the intersection of technical precision and entrepreneurial hustle.

ABOUT ME

My engineering instinct showed up early. I was buying broken iPods, fixing them, and flipping them for profit on my family room floor before I could drive. Real estate changed everything. Sophomore year at UConn, my Zillow search filter quietly switched from "For Rent" to "For Sale," and I never looked back.

That switch led me to The Vinton, a distressed Victorian Tudor that became the first property and the foundation of MAC Development Co. Since then I've executed the BRRR strategy across multiple properties, built iOS apps, run a landscaping business, and managed high-stakes infrastructure projects for the MBTA. Each chapter sharpens the same skill: seeing the angle everyone else misses.

My UConn mechanical engineering degree gives me the technical vocabulary. My edge comes from being willing to get into the weeds with contractors, with city permitting, and with a portfolio that has maintained zero vacancy since day one.
