Brett Lavalla is a UI Engineer with a decade of experience building high-performance, accessible web and mobile interfaces used by millions worldwide. Based in Cupertino, he specializes in native object-oriented JavaScript, HTML5/CSS3 (including advanced 3D animations), WebKit optimizations, and accessibility-focused engineering. At Facebook he contributed notable accessibility inspection and navigation improvements to major Android UI projects—adding accessibility hierarchies and tooling to widely used repos like Stetho, Litho, and Facebook’s screenshot testing framework. His background includes UI leadership at Apple and hands-on interactive work across startups and academia, giving him both product sensibility and deep front-end craftsmanship. Brett is as comfortable squeezing milliseconds out of rendering pipelines as he is surfacing why a view is ignored by accessibility services—a practical blend of performance and inclusivity.
