01 / About

Data wiz.
Creative mind.
Growth driver.

I'm a Performance Marketing & Growth Strategist based in Berlin with a deep passion for turning messy data into clean, actionable strategy. With a background spanning digital marketing, analytics engineering, and UI design, I operate where data science meets business impact.

Currently at PayTR driving acquisition and retention through intelligent, data-led campaigns. I manage end-to-end analytics infrastructure — from server-side tracking to BigQuery pipelines to Looker dashboards.

Outside work, I'm deep into an AI Development Module at Marmara University (in collaboration with METU, Bogazici & ITU) — exploring the intersection of AI and growth strategy.
