Profile
With a background in Management, Economics, Computer Science and Data Science, I have a diverse set of knowledge that can be applied to many fields. I am especially interested in web design and development, user experience (UX) and user interface (UI) design, iOS development, as well as data analysis and visualization.
I received my Master's degree in Information Science from Cornell University with a focus on Human-Computer Interface (HCI) Design. I am incredibly curious about applying my knowledge to construct interfaces that improve the user experience. I am well-versed in the design, build and test process and have taken many projects from initial sketch to production, either as a mobile app or full-fledged web application.
