"Whether you believe you can or you can't, you are right."
Born and raised on the Jersey Shore, I've always been drawn to building things—first out of necessity, then out of curiosity, and eventually as a way of life. I left high school early to pursue college, and not long after, left college to pursue something else entirely: learning by doing.
CAD, 3D printing, full-stack development, manufacturing, business—none of it came from a single path. It came from sitting down, breaking things apart, figuring them out, and putting them back together better than before.
What I build tends to live in the gaps—tools, systems, and platforms for people who are underserved or overlooked. From specialized equipment for hatmakers to custom 3D-printed hardware for craftspeople, to software designed for niche industries, the common thread is simple: I create things that didn't exist when someone needed them.
The Tinker Group was built as the foundation for that work. It's not just a company—it's a workshop. A place where ideas move quickly from concept to reality. Every product, every platform, every brand under it shares the same philosophy: solve real problems with practical, well-designed solutions.
Looking forward, the mission is clear—develop software and systems that empower designers, makers, and builders across industries. The goal isn't just to create tools, but to remove friction. To give people the ability to design faster, produce smarter, and bring ideas to life without unnecessary barriers.
Today, The Tinker Group supports a growing portfolio of projects spanning physical products, SaaS platforms, and automation systems—all built with a focus on precision, usability, and independence. It's a one-person operation by design, driven by a belief that small, focused teams can create outsized impact.
I split my time between Andreas, Pennsylvania and Brooklyn, New York—usually behind a desk, inside a codebase, or next to a 3D printer.
I'm always interested in conversations around hat-making, 3D printing, manufacturing, and building software for industries that larger companies tend to overlook. hello@thetinkergroupllc.com
