I am a product-minded eCommerce engineer with 25 years building and optimizing online stores end-to-end. I spent eight years on Magento delivering 20+ webshops across industries, six years on Spryker powering Swiss enterprise retail (aldi-now.ch, jumbo.ch, sabag.ch). I am currently transitioning to the Shopify ecosystem with active certification in progress. I also work with Claude Code as a daily AI-assisted development tool to speed up delivery and improve code quality. I own the full development lifecycle—from design and implementation to code reviews and deployment—driving performance, scalability, and SEO improvements. I thrive on solving complex integrations (ERP/SAP, CRM, payments), leading cross-functional teams, and shipping practical features daily using modern stacks and AI-assisted workflows.
