PROFILE

Vladyslav Shuliar

Vlad Shuliar developed and expanded core data management and analytics capabilities across several Pharmaverse repositories, including pharmaverse/blog, pharmaverse/admiral, and pharmaverse/pharmaversesdtm. He recreated a lost ECG data script in R, documenting the process in a reproducible technical narrative to support open-source onboarding and transparency. In pharmaverse/admiral, he improved test coverage for key data transformation functions using R and enhanced documentation to streamline validation. For pharmaverse/pharmaversesdtm, Vlad broadened SDTM dataset coverage and refreshed documentation, improving regulatory readiness and discoverability. His work demonstrated depth in R programming, data management, and technical writing, with a focus on maintainability and community knowledge sharing.
