About

I’m a developer passionate about crafting accessible, pixel-perfect user interfaces that blend thoughtful design with robust engineering. My favorite work lies at the intersection of design and development, creating experiences that not only look great but are meticulously built for performance and usability.

Currently, I’m building data-driven applications at Bear Cognition. In the past, I've had the opportunity to develop software across a variety of settings — from large corporations like Charles River Labs to dynamic logistics environments. Whether I'm optimizing database performance or architecting serverless React apps, I love solving hard problems with clean code.

When I'm not at the computer, I'm usually hanging out with my wife and son, trying to catch a wave at the beaches here in Charleston, or playing guitar.
