Precision CSS
Token-driven systems, logical properties, and layouts that hold up from 360px to 4K.
I’m Avery Quinn, a senior frontend engineer specializing in semantic HTML, modern CSS architecture, and accessible product experiences — without relying on JavaScript frameworks.
About
A decade of shipping interfaces where typography, structure, and performance do the heavy lifting.
I build frontend experiences that read like well-set publications — clear hierarchy, intentional whitespace, and CSS that scales. My work sits at the intersection of brand, accessibility, and engineering craft. Whether it’s a marketing site, a product UI, or a design system foundation, I focus on maintainable HTML and CSS that teams can trust.
