I'm Marco, a NYC-based UI Engineer who has spent over a decade architecting and shipping production UI on high-traffic, multi-brand digital platforms. I build the design systems, component libraries, and accessible front-end architecture that scale across brands and codify engineering practices for cross-team adoption.

I specialize in building accessible, performant web interfaces and the design systems that power them, with modern tooling like React, Next.js, and TypeScript on top of a strong foundation in semantic HTML and CSS architecture. My work is CSS-first to minimize JS dependencies, with components designed to scale across multi-brand platforms.
Over a career spent between e-commerce and enterprise SaaS, I've partnered with Product, Design, UX and Engineering to translate design intent into high-fidelity, scalable code. At FullBeauty Brands I architected a design system scaling across 19 brands and spearheaded the front-end migration from SFCC SiteGenesis to SFRA.
My focus is the UI/component layer, with reusable systems, accessible patterns, and component APIs designed for cross-team adoption.
Architected and shipped a design system scaling across 19 brands. Design tokens via Sass and CSS Custom Properties, a CSS-first reusable component library with responsive cross-browser support, and documentation for component states and usage. Distributed as a required dependency, packaged with Webpack as a versioned private npm module powering both SFCC and headless codebases.
CSS-first is an architectural choice, not just a styling preference. Less JS at runtime means faster initial paint, simpler component state, and cleaner cross-browser behavior. I default to CSS for theming, transitions, and state where I can.
WCAG 2.2 AA isn't a polish pass. It shapes semantics, focus order, keyboard flows, and the component API from the first line of code.
Core Web Vitals translate directly to revenue. I default to CSS over JS, lazy-load below the fold, right-size imagery, and measure before shipping.
The seam between design and engineering is where systems hold up or fall apart. I pressure-test interaction patterns with designers and shape the specs before they reach implementation.
Architected a design system scaling across 19 brands (Sass + CSS Custom Properties tokens, CSS-first component library, packaged via Webpack as a versioned private npm module). Built the UI/component layer of a headless commerce app (React, Next.js, TypeScript) delivering accessible, A/B-tested SSR components across Checkout, Search and PDP, integrated via REST APIs. Established cross-team UI standards including a 90+ Lighthouse accessibility minimum, reducing recurring UI fix work by ~25%. Spearheaded the front-end migration from SFCC SiteGenesis to SFRA with an isolation approach that made the design system the company-wide standard.
Built and optimized components for high-traffic Browse & Search pages in Backbone.js, Marionette and Sass. Iterated through A/B tests, shipped accessible components into a company-wide style guide and pattern library, raised Jest coverage past 80%, and shipped CSS-animation, lazy-load and responsive performance wins.
Engineered reusable, accessible components and templates for an enterprise SaaS drag-and-drop site-builder using React, Redux and Sass. Delivered multi-tenant theming for Fortune 500 clients on a shared component foundation. Established CSS standards across the team and advocated for CSS-first implementations to minimize JS dependencies.
Built custom branded micro-sites for influencer-marketing clients in JavaScript, CSS3 and Foundation. Implemented D3.js data-visualization features for platform analytics.
Completed the 12-week Web Development Immersive, then hired on contract to mentor students through the same program: Ruby on Rails, Git, JavaScript, testing, and programming methodologies.
Managed web content across the organization.
First hands-on experience with HTML and CSS, managing organizational websites.
Open to conversations about roles, collaborations, or design system work. Based in New York; comfortable remote or hybrid across US & EU hours.
