What I'm looking for

I am seeking a role that fosters collaboration, innovation, and growth opportunities.

I am an analytical and agile data analyst with a Ph.D. from Cornell University, specializing in transforming complex data into actionable insights. My experience spans high-impact, fast-paced environments where I have successfully driven decision-making through R-based analytics and stakeholder collaboration. I take pride in my ability to design KPIs and improve operational efficiency, ensuring that data informs strategic decisions.

Throughout my career, I have achieved significant milestones, such as reducing tutor churn by 25% through multi-factor regression analysis and enhancing writing quality assessment accuracy by 20% with an NLP pipeline. My role as an AI Tutor at xAI has allowed me to analyze large-scale datasets, achieving quality scores exceeding 85% and increasing task throughput by 30% through effective survey data analysis.

In addition to my technical expertise, I have a strong background in academia, having served as a Faculty Chair and Assistant Professor at Istanbul Health and Technology University. Here, I led analytics-based curriculum design, improving student outcomes by 15%. My commitment to mentoring and fostering evidence-based teaching methods has further enriched my professional journey.
