Hi, I’m Erdinç Ciftçi. I’m a Growth Manager specializing in e-commerce funnels and performance marketing for DTC brands. I’ve helped clients from startups to Wikimedia Deutschland achieve measurable revenue growth through funnel optimization, Klaviyo automation, and rigorous A/B testing. I enjoy turning data into human-friendly UX, running rapid prototype cycles, and delivering accessible interfaces that convert—across web and mobile. When I’m not optimizing funnels, I explore web3 for creatives, micro-credential courses, and helping teams ship impact-driven experiences.…Hi, I’m Erdinç Ciftçi.
