Top SchoolTom Trenka is a senior software engineer specializing in analytics and data visualization with nearly two decades of experience building web applications for companies like IBM, Adobe, Cisco, and Sun. An early and influential contributor to the Dojo Toolkit—serving as DojoX project lead—he has deep front-end expertise in creating performant UI components and skins (notably contributions to Dojo core, Dijit, and the dgrid ecosystem).

Based in Saint Paul, MN, Tom pairs a rare academic background (PhD in Music Theory and Composition) with pragmatic engineering, bringing pattern recognition and creativity to UI and data challenges. His public portfolio (github.com/ttrenka/snippets) underscores a long history of practical open-source contributions that shaped early modern JavaScript toolkits.
