I'm Audrey, a frontend engineer who builds interfaces that feel effortless to cross — like a well-designed border checkpoint where nobody notices the queue. For the past eight years I've turned complex products into fast, accessible, carefully crafted web experiences.

My home territory is React and TypeScript, with a deep respect for semantic HTML and modern CSS. I care about design systems, Core Web Vitals and WCAG compliance, and I like working in the space between design and engineering where details decide whether a product feels trustworthy.
