About Janne

Shopify Expert for Store Builds, Customization & Migrations


I help Shopify merchants and digital agencies launch, customize, and improve Shopify stores that are reliable, easy to manage, and built for long-term growth.

I work exclusively with Shopify and handle projects ranging from full store launches to advanced theme customization and platform migrations. My approach is structured and practical: I focus on clean implementation, clear communication, and solutions that continue to work after launch—not just on demo day.

Typical projects include Shopify store setup, theme customization with custom Liquid sections, metafields and metaobjects, Theme v2 upgrades, and safe migrations from other platforms. I also support ongoing improvements such as UX refinements, performance fixes, and merchant training.

Clients value that I explain technical decisions in plain language, proactively suggest better options, and take full ownership of the outcome. I am used to working directly with founders as well as alongside designers and agencies.

If you are looking for a Shopify partner who combines technical depth, reliability, and calm execution, I am happy to discuss your project.
