PROFILE
Nicholasgaudet
Nicolas Gauvin developed robust data cleaning, transformation, and machine learning pipelines for the clessn/datagotchi_federal_2024 repository over four months. He engineered end-to-end workflows in R, focusing on lifestyle, user preferences, socio-economic status, and demographic datasets. His work included refactoring raw data into analysis-ready formats, standardizing categorical variables, and implementing feature engineering for improved reporting and modeling. Nicolas also built a multinomial logistic regression pipeline for vote-choice prediction, ensuring reproducibility through harmonized data structures and clear commit practices. By addressing both data integrity and analytics readiness, he enabled more reliable downstream analysis and streamlined the project’s business intelligence capabilities.
