Career Turning Point

During my time at Callaway Golf, I was fortunate to work with senior developer Jim Weirich, who introduced me to Ruby and LISP. This exposure sparked my interest in functional programming paradigms and ultimately led to a significant shift in my career trajectory.

My growing passion for Ruby and functional programming principles inspired me to leave Callaway when Jim did, allowing me to pursue opportunities focused on Ruby development and, later, Ruby on Rails. This pivotal experience at Callaway Golf marked the beginning of my journey into a new programming ecosystem that would shape my future career.
