About

I’m an Industrial Engineering graduate who co-built and launched Calnote, an AI-powered calorie tracking app that reached 30,000+ total downloads and a top-10 App Store ranking in Turkey. I enjoy turning user feedback into product decisions—whether that’s shaping early features with a founding team or running growth experiments to improve funnels and conversion.

In my roles, I’ve combined product & growth with hands-on marketing execution: I designed influencer and affiliate strategies, managed social media accounts, and used analytics to support data-driven decisions. I also bring direct customer-facing experience from selling and supporting gym memberships, helping prospects choose the right plan based on their goals.
