My expertise in Shopify
Shopify is the secret weapon of brands that want to sell online without worrying about the tech. I build custom shops that grab attention and turn every visit into a sale.

Forget generic templates. I code your Shopify theme in Liquid from start to finish. Your shop gets a unique design, an optimised path to purchase and a visual identity that stands apart from your competitors at first glance.

Shopify shops designed to sell
Shopify powers millions of shops worldwide, from start-ups to major brands. Its decisive advantage is fully managed technical infrastructure: hosting, security, updates, SSL certificate. It's all taken care of. My role is to turn that solid foundation into a shop that looks and feels like your brand. I code custom Liquid themes, optimise every step towards the checkout and make sure your product pages rank at the top of Google. You look after your products, I look after the technology. If you'd like to set everything out from the start, request a quote for your Shopify shop. Design, logo, product pages and ads setup: we define the scope together.

Frequently asked questions about Shopify
Can't find what you're looking for? Get in touch directly, I always reply within 24 hours.
Get in touchShopify is the most reliable e-commerce platform in the world. The technical infrastructure (hosting, security, SSL certificate) is fully managed by Shopify. You don't have to worry about updates or server outages. You focus on one thing: selling your products.
A fully custom Shopify theme, coded in Liquid with a unique design, your payment methods integrated and complete SEO optimisation, starts at CHF 3,000. The Shopify subscription (from CHF 36 per month) is paid by you and gives you access to the entire technical infrastructure.
With a developer, yes, without limits. Shopify's development language (Liquid) makes fully custom shops possible. I don't just install a paid theme and change the colours. I code your theme from scratch so it matches your visual identity exactly.
Absolutely. Shopify handles multiple currencies (CHF, EUR) and Swiss taxes natively, and integrates with local payment solutions such as TWINT. I also set up Swiss carriers (Swiss Post, DPD) so shipping costs are calculated automatically.
Yes. From WooCommerce, PrestaShop or Magento, I handle the full migration: products, customers, orders and SEO redirects. Your new Shopify shop picks up where the old one left off, with no loss of traffic or data.
