About Fabian

Die letzten fünf Jahre war ich als Frontend Developer bei feelgrounds.de angestellt, einer Shopify Plus Brand im Barfußschuhsegment, bevor sie Ende 2025 verkauft wurde.

Dort habe ich das Theme entwickelt und erweitert, neue Funktionen gebaut und dafür gesorgt, dass der Store technisch sauber läuft. Außerdem habe ich Landing Pages für Produktlaunches umgesetzt und UI & UX entlang der Customer Journey kontinuierlich verbessert.

Parallel dazu habe ich gemeinsam mit der deutschen CRO-Agentur Dripagency ein A/B Testing Programm aufgebaut, das auf datenbasierten Hypothesen beruhte und in dieser Zeit 27% nachweisbares Umsatzwachstum gebracht hat.

    June 2021 - November 2025 (4 years and 5 months)
    During this time I worked in-house at Feelgrounds, a Shopify Plus barefoot shoe brand, supporting their growth from ~€2M to over €6M in annual revenue. Starting with development and design, I also built and ran their structured A/B testing program over the last two years. In the last calendar year alone, we ran 16 experiments with 5 winning tests, contributing to a measurable ~27% revenue uplift.

    On the frontend development and design side, I worked on a wide range of store optimizations over four years, including menu redesigns, landing pages for new product launches and the post-purchase experience, page speed optimization aligned with Google's Core Web Vitals, and improvements to the product image gallery.

    The extended in-house experience also taught me how to work closely with marketing, copywriting, design, and product teams. It gave me a comprehensive understanding of what makes a successful Shopify Plus brand, and helped me establish processes I now bring to every project.
