    paper Premium E-commerce + Inventory App

    https://www.twine.net/signin

    Dual project for a Swiss premium cigar distributor: high-end WooCommerce store combined with a custom internal inventory management app in Node.js and React.

    The challenge was to build a premium eCommerce with zone-based shipping calculations, alongside an internal inventory tool replacing the team’s manual Excel spreadsheets.

    eCommerce work:
    • WooCommerce customized for premium positioning
    • Dynamic shipping cost calculation by customer location
    • Real-time stock synchronization between storefront and back-office
    • Secure payment integrations

    Inventory app (Node.js/React):
    • Full-stack inventory management tool
    • Automated low-stock alerts and reorder notifications
    • Simplified UI for non-technical daily use
    • WooCommerce synchronization

    Results: Premium eCommerce live and operational, internal tool replacing manual Excel workflows, and real-time stock visibility for the team.

    paper Variation Selector & Custom Vacation Mode

    Swiss e-commerce specialized in Apple products, requiring fine-grained variation management (color, capacity, generation) and a vacation handling system for the owner’s absences.

    The challenge was to build a smooth shopping experience on a complex variation catalog, and to handle owner absences without losing customers.

    Key contributions:
    • Developed an advanced WooCommerce variation selector with dynamic color filtering.
    • Implemented multi-level e-commerce filters for enhanced catalog navigation.
    • Created a custom “vacation mode” with automatic customer notifications about delivery delays.
    • Optimized performance using WP Rocket and Cloudflare.
    • Integrated payment and stock management systems.

    Results: Smooth product experience on a complex catalog, reduced cart abandonment due to variation confusion, and business continuity ensured even during owner absences.
