MADISON, CT · JUNIOR, CIVIL ENGINEERING BOUND
I build things that actually have to hold up.
I'm captain of my robotics team, about to commit to Civil Engineering, and I've built two golf software products that people actually use.

ENGINEERING
How I actually build
The parts of the work that don't show up in a screenshot.
Civil Engineering
I'm 99% set on studying Civil Engineering. I designed and built a house from scratch, floor plan, structure, all of it, in an Architectural Design class.
Robotics
I'm captain and lead engineer on my school's robotics team. I run the design process end to end: CAD, prototyping, competition day.
Systems, not just screens
Once a platform touches real money, the interesting engineering stops being visible. Building GolfTradr meant adding advisory-lock payment idempotency so trades can't double-charge, SSRF protection, 3D Secure enforcement, and a Cloudflare WAF layer with bot-fight mode and rate limiting.

ABOUT
Mostly building. Also golf.
I'm 99% set on Civil Engineering, with a minor in Entrepreneurship.
T1 at the DeNicolo Memorial Junior Open this year, shot 69. Helped lead Daniel Hand to the CT State Championship team title, 4th individually with a 73. I play CTPGA and Hurricane Junior Golf Tour events. GolfTradr and GripFitr both started because of things that annoyed me on a golf course or in a pro shop.
