Page Assembly & Responsive Production

Once designs and copy were finalized, I led production across desktop, tablet, and mobile. I partnered with Design Technologists on complex interactions, and built the remaining site in CMS.

I handled all asset production — including localized imagery, video, and animation — and ensured everything was optimized, responsive, and performance-ready across breakpoints.

Production Figma File

A page is never just a page.

I built and maintained a highly structured production file to support asset generation at scale across breakpoints and locales.

Assets were modular, systematically named, and optimized for reuse across Contentful, Box, and Figma — making updates faster and enabling other teams to self-serve when needed.

One Page. Eight Markets. Eleven Languages.

Localization was one of the most complex parts of working for a global company. I owned it end-to-end, from coordinating translations and adapting assets, to running QA with native speakers to make sure each experience felt right for that market, not just translated.

I maintained a reusable template and module library in Contentful to support scalable web production. The system provided pre-built, on-brand components that allowed teams to create pages quickly and consistently, without starting from scratch.

I worked closely with the Design Systems team to test components and ensure alignment with the Figma library, then owned the library in Contentful — keeping it up to date, production-ready, and easy to use.

This reduced build times by 50% and lowered the barrier to entry for teams working in a complex CMS, enabling faster and more consistent output across the company.

AI enabled us to automate the creation of 100 SEO programmatic landing pages, dramatically reducing production time and manual effort.

This freed up time for higher-impact work: handling ad hoc tickets, exploring new AI workflows, and spending more time on creative problem-solving.

I tested real scenarios, resolving edge cases, and helping define workflows the broader team could adopt.

Once it was in a stable place, I created onboarding documentation and trained other Production Designers so the team could effectively use the tool and scale its impact.

Since we're on the topic...

AI was part of my daily workflow, used to improve speed, consistency, and output quality across production. And yes, I vibe-coded this portfolio. So many learnings.
