    Frontend Developer – Implementation of a custom sales funnel


    Situation
    An e-commerce client specializing in repair services needed to integrate two distinct order flows into their Shopify site.
    The goal was to offer a fluid and personalized user experience based on the type of repair requested.

    Task:
    I was responsible for:
    - Supporting the client on the technical aspects
    - Integrating two sales funnels (“classic repair” and “motherboard repair”) from the provided Figma mockups and adapting them to Shopify's technical constraints
    - Adapting these funnels within the premium Concept theme used by the store.
    - Adding a module allowing the user to enter additional information directly within the order process.

    Actions:
    - Integration of Figma mockups into the premium Shopify theme.
    - Development of specific logic to differentiate the two types of funnels.
    - Implementation of custom fields to collect necessary information based on the chosen service.
    - Testing and adjustments to ensure compatibility with the theme and optimal user experience.

    Results:
    - Delivery of a personalized, fluid sales funnel compliant with the mockups.
    - Improved user experience with clear, repair-type-specific flows.
    - Increased operational efficiency through automatic collection of additional information during the order process.
