Infinite-scroll sliders, conditional product logic, Routines metafield architecture — a 7 to 10-hour expert intervention on FullStack 2.0 to finish what the team had already started well.
Friction points specific to FullStack 2.0
Séfia had migrated from FullStack 1.0 to 2.0 in-house. Certain theme-specific behaviors — sliders, conditional logic by product type, metafields — required fine FullStack expertise the internal team didn't have.
Conditional product logic with no template duplication
The “30-day money-back guarantee” block had to show only on cotton pads — not on every product. The Routines pages (morning/evening) required a metafield architecture with conditional step display, with no template duplication and no empty sections.
High-impact visual and UX finishing touches
Infinite-scroll sliders with direct mouse interaction on desktop, blur on the transparent homepage header, a Trustpilot anchor smoothly scrolling to product reviews, a visual separator between horizontal text blocks — precise visual details that define the site's final quality.
Séfia had handled the FullStack 1.0 to 2.0 migration themselves. A skilled technical team, an already solid result — but several precise finishing points remained to reach the level of experience they wanted.
The Deployer stepped in as a FullStack expert on a scope defined upfront: slider behavior, conditional logic on product guarantees, blur effect on the header, smooth Trustpilot anchor, homepage separators, metafield architecture for the Routines pages.
Séfia is available in more than 500 pharmacies across France and its overseas territories, with over 1,000 Trustpilot reviews at 4.4/5. An established brand that runs its infrastructure in-house — one that doesn't need an agency to operate, but a targeted expert to unblock what resists.
The golden rule of a successful migration: don't start from scratch. We first faithfully replicated the existing setup to protect performance, then leveraged FullStack's native capabilities to eliminate friction points.

The FullStack Theme is not a generic theme. It is 6 years of expertise condensed into a single codebase — 100% proprietary and built for performance.
Every feature is built natively into the theme. No conflicting third-party apps, no asynchronous loading, no hidden technical debt.
FullStack is 100% proprietary code — not a third-party base, not a fork. It is the culmination of 6 years of cross-functional expertise: Shopify development, CRO, UX design, A/B testing, analytics, marketing, and human psychology.
Migration empowers teams to iterate independently without external dependencies. Every FullStack update automatically enhances your store.
“Séfia had done the migration on their own — they're a technical team. They brought us in on the details that resisted: slider behavior, conditional logic on the guarantees… There's a point where specific FullStack expertise speeds everything up.”
