Sean Matthew Viacrusis

My definition of a Problem Solver:
Someone who understands the problem well enough to know what to build, and what not to.

I’m Matthew. I work best where business meets technology. I understand what clients need, figure out what makes sense, and build solutions around it.

Sometimes that’s a custom AI model, an API, or a physical prototype. Other times, it’s a business strategy, a convincing pitch, or simply asking the right questions.

I speak business, think in systems, and build in code.
