Flavor Remix — a build-your-own giftbox for M&M'S

Owned large parts of Flavor Remix — M&M'S' build-your-own giftbox — end to end: its dedicated v2 product page, a rebuilt review-before-you-buy flow, an accessories drawer, and customer image upload with moderation and reupload. All on a commercetools model reworked to treat flavor as a first-class attribute.

Flavor Remix lets customers assemble a custom giftbox, so its product page can't be a static PDP — it's a builder. I built the v2 product detail experience for it: composing the mix, adapting the accessories flow into the page, and refining styling and layout so a configurable product still reads like a polished storefront page.

The review step is where a custom build becomes an order, so it had to be exact. I rebuilt the Review v2 flow — adding the assembled giftbox to the review page, surfacing accessories in a drawer gated behind a feature flag for safe rollout, and making sure what the customer confirmed was precisely what they'd receive.

Because customers upload their own images onto a physical printed product, the flow needs guardrails: upload with image rejection for anything unsuitable, and reupload so a rejected image doesn't dead-end the order. Moderation runs before anything reaches production.

Personalization is only as clean as the catalog behind it. I promoted flavor to a first-class commercetools attribute — a stable flavor id, localization removed where it didn't belong, and the old free-text field deprecated — so the builder reads structured data instead of strings.
