    Complete E-commerce Development
    E-COMMERCE
    August 2025 - August 2025
    Aix-en-Provence, France
    A client came to me with a clear idea: they wanted to launch an online store in the comfort & well-being niche, but didn't know where to start. Their goal was simple: an elegant, smooth site, ready to sell from day one.

    I assisted them from A to Z. I configured the entire technical part of Shopify (domain, payments, shipping, legal notices) and connected their Print-on-Demand supplier. We then selected 4 products together that were consistent with their brand.

    Each product page was crafted to tell a story and highlight the real benefits for their future customers.

    On the design side, I focused on a simple and pleasant experience: an immersive homepage, intuitive navigation, and a premium visual universe, both calming and futuristic. I also optimized the entire purchasing process so that each customer could order frictionlessly, from the cart to checkout.

    In less than 7 days, they had a turnkey store: beautiful, functional, and above all, aligned with their high-end brand image.

    EDUCATION AND E-LEARNING
    September 2022 - August 2025 (2 years and 11 months)
    Aix-en-Provence, France
    🎓 Graduated with a Bachelor's in Business and Marketing, now a Commercial Development Manager, I have developed a rare expertise at the intersection of business, digital marketing, and web design.

    Specifically, I help transform educational or marketing projects into effective and engaging digital experiences, through:

    Complex project management: commercial and marketing steering, team coordination, go-to-market strategy.

    Front-end integration (HTML, CSS, JS): creation of modern web interfaces, interactive educational materials, high-performing landing pages.

    Each interface or module is designed to convert, train, and engage users, not just to 'look good'.
    💡 My advantage: I speak the language of both business decision-makers and developers/designers. This allows me to ensure consistency between marketing strategy, visual design, and technical integration.
