Gero Keller
Founder & Shopify Engineering Partner
I grew up during the ecommerce revolution, building and scaling online businesses from the early Rocket Internet days to Vodafone and Learnship. As Head of Engineering at a Rocket Internet automotive marketplace, I worked in true hyperscaler mode: fast iteration, data-driven decisions, and platforms designed to cope with sudden spikes in traffic and demand.
Later, with crvsh, I ran a product studio that operated like an in-house agency for Vodafone. We owned the full digital customer journey for launches like V by Vodafone and Vodafone Smart Tech – from discovery and UX through to the commerce flows that actually convert.
Most recently, as CTPO at Learnship, I rebuilt the ecommerce setup from scratch, moving from a patchwork of in-house systems, Magento Cloud, and Salesforce Commerce Cloud to a focused Shopify-based stack that enabled new business models and faster iteration.
Today at 27street, I combine that experience to help merchants design and implement Shopify setups that are commercially sharp, technically robust, and ready to scale.
