results delivered.

about me
export const ellen = { name: "Ellen Goettsch", role: "Freelance Growth Engineer", tagline: "Experiments built, results delivered 🚀", sayHello() { return `Hi, I’m ${this.name} — ${this.role}. ${this.tagline}`; } }; // Example: console.log(ellen.sayHello());
Hi, I’m Ellen — a freelance growth engineer who designs, builds, and analyses A/B experiments end-to-end, driving measurable results through lean growth sprints.
My background spans marketplaces, e-commerce, fintech, and mobility — working with brands like Goboony, SEAT, Volkswagen, and Randstad. What I love most: turning growth ideas into working experiments that ship fast, scale well, and deliver measurable results.
I combine hands-on coding (front-end, tracking, automation) with growth strategy (hypotheses, funnels, onboarding). No waiting on backlogs, no endless meetings — just experiments that run.
