📍 NYC / Remote
I'm Matt. I'm a software engineer with six years of experience. Primarily, I have worked in the adtech space building applications to manage and deliver international advertising campaigns.
Lately, I have applied my skills freelancing. I just collaborated with AllTrails, the most trusted and used outdoors platform in the world, and their expansive Rails + React app. I practice object-oriented design, UI engineering, as well as collaboration on rugged teams.
I'm a voracious learner, eager to implement a fresh `${ESNext}` feature or the decades-old pattern of object aggregation. I enjoy organizing and writing code that harmonizes with the needs of my team. When I work, I make sure to thread the aims of the big picture through the daily goals I set.
I'm originally from NYC and won't leave for bigger closets.
I love to practice Spanish and bake Add walnuts .
