Hi, I'm Sia Karamalegos.
I'm a freelance web developer and web performance engineer. Most recently, I was working at Shopify, helping merchants make their online stores faster. I also took those learnings back to the platform to make wider changes such as implementing the section.index and default lazy loading features in Liquid. I built out a large part of performance.shopify.com and its blog with the help of my team.
I organize the Eleventy Meetup and Durham Social Hack Night. I'm a Google Developer Expert in Web Technologies specifically for web performance. As a developer, I love building things that help make people's lives easier. Check out Theme Vitals for a data analysis tool on Shopify theme performance and Coder Ipsum for a fun developer-inspired ipsum text generator.
As a person, I love making developer's lives easier through teaching, speaking, and mentoring. You can find more information about me and the topics I speak about on my speaking page. I talk about front-end topics such as web performance, JavaScript, static site development with Eleventy, and optimizing Shopify storefronts.
