Summary

Senior🎓
Top SchoolGerald Lewis is a seasoned full-stack software engineer with 15 years of experience building interactive web and mobile experiences, currently focused on React Native, TypeScript, accessibility, and animation at MojoTech. He founded Pennant Co, where as sole developer he pushed browser limits—implementing HTML5/WebGL/Canvas systems, custom font and DOM/CSS parsers, and mobile touch-aware ad experiences. Early career work in ActionScript and rich media delivered high-profile campaigns and large-audience microsites for brands like Volvo and Kraft, blending creative direction with technical execution. Gerald’s open-source contributions include bug fixes and compiler-level enhancements to the prominent CoffeeScript project, showing deep understanding of language internals and compilation semantics. Based in Old Lyme, he pairs a BFA background in film and animation with low-level browser knowledge to create performant, expressive interfaces. Colleagues describe him as an engineer who enjoys digging into platform internals as much as crafting polished user-facing interactions.
