Fabian EppingerBased in Munich A little about me
A developer with a
commercial perspective.
My background in performance marketing shapes how I build software. Working with e-commerce brands taught me to look beyond the interface: at the customer journey, the operations, and the business behind them.
I've been on both sides, managing €100k+ daily ad spend, optimizing conversion rates, building retention strategies. The biggest wins came from building tools: landing pages that convert, Shopify apps that scale, marketing dashboards that show where revenue actually comes from.
Today, I bring that perspective to Shopify projects, full-stack applications, and AI systems. I like understanding how things connect, then making them work better together.
