OLEUS is a Nestlé venture: mitochondrial health shots rooted in Swiss science. Through Bundl I joined as designer and developer on the production storefront, working alongside Montana Mertens, Bundl's senior designer, who led the design, from the Figma design system to the custom Shopify theme code running at oleus.com.

From Figma system to theme code

The storefront runs on a fully custom Shopify theme. Montana led the design; my work sat on both sides of the usual handoff, extending pages in her Figma system and building them as Liquid sections and templates. Staying close to both ends meant the design intent survived all the way to production, down to the type scale and the easing curves.

A system the team can build with

The theme is a scalable component build, not a set of hard-coded pages. Every section ships as a reusable, configurable unit with its own schema, so the brand team assembles new pages and campaigns straight in the Shopify editor. Layouts stay on brand without a developer in the loop, because the guardrails live in the components themselves.

Built to sell, not to demo

This is a live store with real customers, real product data, and a review count that keeps moving. Every design decision had to hold up against changing content and a running catalog, not a frozen staging environment. That constraint shaped the system more than any moodboard did.

Shout out to Montana Mertens for the great design work this storefront is built on, and to Jan Van Fraeyenhoven for setting up all the tracking behind it.
