Senior UX Researcher Yesim
I own end-to-end UX research for a global telecom product with 3 million users, supporting strategic decisions across acquisition, activation, plan selection, paywall, checkout, retention, and customer trust. I lead mixed-methods studies including interviews, usability testing, surveys, desk research, competitive benchmarking, concept evaluation, and behavioral segmentation for international audiences.
I drove paywall and purchase-flow optimization research that increased paywall-to-purchase conversion to 11%, and identified UI improvements that raised homepage CTR to targeted product pages to 29%. I define research roadmaps with Product, Design, Growth, and Marketing; lead experimentation; and create reusable templates, survey standards, insight summaries, and decision-oriented reporting.
