    Howdy! I am a full stack engineer who loves a difficult challenge to push me to my limits. I love being a software engineer because I learn new things every single day and I'm faced with unique challenges on the regular. But what truly excites me about building new applications is the opportunity for me to be creative and to build something beautiful with my own hands. As part of an interdisciplinary clinical team in my previous career, I learned to exchange expertise in order to provide patients with the best care possible. Now I use these same skills to act as a productive member of a development team; sharing the skills I have and absorbing the skills that I need in order to optimize outcomes. As a student at HackReactor, I obtained hard skills in JavaScript, React, Node.js, express.js, SQL, MongoDB, AWS and much more. As a software engineering mentor at Galvanize, I teach students in the Advanced SWE immersive these skills and other computer science fundamentals.
