Founder, MAC Development Co.  ·  B.S. Mechanical Engineering, UConn

I'm the kind of engineer who thrives on what others call impossible. Whether managing MBTA rail shutdowns on tight overnight windows or converting a 1935 stone church into a mixed-use asset, I operate 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.

Built and manage a growing portfolio of value-add residential and adaptive reuse properties. Oversee all aspects of the BRRR process — acquisition, renovation management, tenant placement, and refinancing. Currently leading the historic stone church conversion, the most complex project in the portfolio's history.

2024 – 2025
FIELD ENGINEER
SPS New England · MBTA Infrastructure

Led field engineering during high-stakes overnight shutdown windows across MBTA Orange and Green Lines. Coordinated track improvement crews, managed material logistics, and ensured zero overruns on a system where every hour over-window carries major costs.

2016 – Present
SERIAL ENTREPRENEUR

A lifelong pattern of spotting gaps and filling them. Launched iOS apps, ran profitable e-commerce operations, and scaled a landscaping business — each teaching new dimensions of operations, customer relationships, and capital allocation that directly inform how I run real estate today.

2018 – 2022
B.S. MECHANICAL ENGINEERING
University of Connecticut

Technical foundation in mechanical systems, CAD, materials, and engineering methodology. Simultaneously launched The Vinton — turning college housing research into a portfolio anchor that has been fully occupied ever since.
