My expertise in PrestaShop
PrestaShop is the most widely used e-commerce engine in Europe. I use it to build solid online shops designed to handle large catalogues and maximise your revenue.
01
Custom shop development
I build your PrestaShop theme from scratch. No generic template. Your shop reflects your brand, loads fast and guides visitors to checkout along an optimised path to purchase.

Selling online takes more than putting a product catalogue on the web. A profitable shop relies on solid technical architecture, a smooth path to purchase and flawless load speed. My PrestaShop expertise lets me deliver shops that don't just display your products. They sell them. From the first click to the order confirmation, every technical detail is designed to maximise your conversion rate and customer satisfaction.

Frequently asked questions about PrestaShop
Can't find what you're looking for? Get in touch directly, I always reply within 24 hours.
Get in touchPrestaShop is an open-source e-commerce CMS built to sell. Unlike WordPress, which is a blog turned into a shop, PrestaShop natively handles product catalogues, stock, carriers, promotions and multi-country taxes. It's the solution of choice for serious online retailers in Europe.
A professional PrestaShop shop, with a custom theme, full setup of payment methods and carriers, and SEO optimisation, starts at CHF 3,500. The final budget depends on the number of products, specific integrations (ERP, accounting) and the advanced features required.
That's the great advantage of PrestaShop. The back office is complete and designed for merchants. You can add products, manage stock, track orders and analyse sales without any technical skills. I also provide a personalised video training session at handover.
Yes, as long as it's configured properly. I make sure the URL structure, meta tags, Schema.org markup (Product, BreadcrumbList) and load speed are fully optimised. Your product pages get indexed quickly and rank effectively on Google.
Online shops need regular care: security updates, database backups, performance monitoring. I offer a monthly maintenance plan so your shop stays fast, secure and up to date without you having to think about it.
