About

With a Master’s degree in Computer Science from the University of Dayton, I currently contribute as a Software Engineer at Citi. My core competencies include developing high-performance Angular 19 front-end features, resolving API integration challenges, and optimizing frontend-backend build performance. I have successfully migrated legacy micro-frontends to a Component Design System, enabling consistent user experiences and reducing UI discrepancies. At Citi, I work collaboratively with cross-functional teams to improve design efficiency and streamline application performance. By leveraging Angular Signals and automated build strategies, I help accelerate development and reduce inefficiencies. My goal is to deliver user-centric, scalable solutions that align with organizational standards while fostering innovation and design excellence within the team.
