Sebastian Lijewski

I’m a Healthcare Data Scientist with a PhD in Pharmaceutical Sciences, bringing a strong analytical and research background into modern data science. I leverage Python and SQL to train, evaluate, and improve machine learning models, backed by advanced statistical analysis and feature engineering. I also work with applied AI capabilities in Python, including LLMs, RAG, and basic/working knowledge of MLOps.

In my current role (2022–present) as Head of Pharmacy at Good Samaritan Hospice, I manage and analyze medication usage data to identify trends, patterns, and actionable insights that support data-driven decisions in healthcare. Previously, as a Scientific technical specialist (2016–2021) in the Department of Chemical Technology of Drugs, I designed and executed experiments, performed complex data analysis, and published findings based on data-driven insights. Across both roles, I combine scientific rigor with data tools and collaborate with medical staff to optimize treatment processes.
