Empyrean Benefit Solutions, Web Systems Engineer

I am a JavaScript enthusiast with a B.S. in Mathematics with Highest Honors from Sam Houston State University. While studying mathematics, I participated in research funded by the National Science Foundation in Knot Theory and Graph Theory and traveled nationally to present significant research results. I began learning JavaScript recreationally and continue to learn more and more professionally as a frontend developer. I currently work for Empyrean Benefit Solutions as a Web Systems Engineer.


While using mobile applications, users intuitively expect fully featured gesture controls such as zooming and panning full screened images. As developers, we have many choices on how to enable these features in our mobile applications. This talk presents a functional programming approach in Typescript for handling gesture events in a mobile application developed with NativeScript. Join a Web Systems Engineer with a mathematics background to learn how to leverage group theory, a field of mathematics, to deliver the features your users want.
