What I'm looking for

I’m looking for a data role where I can use SQL, Python/R, experimentation, and visualization to improve performance in advertising or operations, collaborate with technical and non-technical teams, and drive faster evidence-based decisions.

I’m a Data Analyst with a PhD in Chemometrics, focused on transforming complex datasets into business insights. I use SQL, Python, R, and visualization tools like Power BI and Tableau to help teams understand performance, optimize processes, and make faster evidence-based decisions.

In my roles across digital advertising and e-commerce support, I analyze campaign and operational data to identify trends, fix bottlenecks, and guide stakeholders using tools like Meta Ads Manager reporting and structured troubleshooting. In my PhD research, I applied statistical modeling, multivariate analysis, and experimental design—improving extraction efficiency by 10% and product quality by 20%—and communicated results through seven peer-reviewed publications, presentations, and mentoring.
