Steven Haesendonckx enhanced clinical trial reporting workflows in the RConsortium/submissions-pilot5-datasetjson repository by delivering four feature updates over four months. He focused on improving Kaplan-Meier plot visualizations and RTF reporting templates, refactoring R scripts for maintainability and clarity while integrating ggplot2 and ggsurvfit for advanced survival analysis. Steven migrated data loading from XPT to RDS to accelerate processing and streamlined report headers for clearer outputs. His work included standardizing function calls, refining statistical table formatting, and adjusting PDF report layouts for readability. Throughout, he demonstrated depth in R programming, data visualization, and statistical modeling, emphasizing robust, scalable reporting solutions.
