About Josi

Shopify expert and developer.
I create custom Shopify stores for entrepreneurs, brands, and e-merchants.
I also work on optimizing and redesigning existing sites.

Throughout my career, I have acquired over 10 years of experience in data.
Today, I put this dual expertise to work for your growth.

With me, you will get:
- A free audit of your existing store
- A website optimized for conversion: optimization of Liquid code, speed, performance, bug fixes
- A custom store: development of your theme from A to Z
- A fluid and clear user experience
- Monthly support: continuous evolution of your store, backups, analysis, and actionable recommendations

Why entrust your project to me?
My strength: dual expertise in Shopify + data
