I'm responsible for Webflow development and QA at xfive, working on both our company websites and client Webflow projects, and supporting quality assurance across our client work. I joined xfive 20 years ago as a senior front-end and WordPress developer, then helped set up our Quality Assurance department and led it for four years, alongside nearly a decade of leading our development standards work.

Along the way, I've written extensively for our blog, on topics ranging from CSS architecture and WordPress to quality assurance, with some posts reaching hundreds of thousands of views. Most recently, I created Cognate, an approach that aligns our Figma design system with Client-First in Webflow for faster, error-free builds. I hold the Webflow Practitioner Certification and the Webflow Way certificate.
