About Lou

Do you want to launch or grow your online store? I am your Shopify expert, specializing in the creation, customization, and optimization of high-performing e-commerce sites.

For several years, I have been assisting entrepreneurs, brands, and SMEs in building their online presence on Shopify. My goal: to deliver a turnkey store that is fast, intuitive, and optimized to convert your visitors into customers.

What I do concretely:

Shopify store creation from A to Z — custom design, custom themes (Liquid), integration of your products and collections.

Development of advanced features — applications, custom scripts, payments, upsell/cross-sell, loyalty programs.

Performance optimization — loading speed, technical SEO, conversion rate (CRO), mobile experience.

Third-party integrations — ERP, CRM, logistics, marketplaces (Amazon, FNAC…), marketing tools (Klaviyo, Meta Ads, Google Shopping).

Migration to Shopify — from WooCommerce, PrestaShop, Magento, or any other CMS.

I work with the latest Shopify technologies (Shopify 2.0, Hydrogen, Headless Commerce) to offer modern and scalable e-commerce experiences.

Let's talk about your project — I will propose a strategy tailored to your needs and budget.
