Tim Kim

Software Engineer · Orlando, FL

While working as a technical solutions engineer, I fell in love with the elegance, power, and accessibility of code. As a result, I quit my job, self-studied computer science, and jumped into coding. I am a mission driven software engineer with a passion for learning, collaboration, and improving the lives of those around me.
