Maria Ladelacruz established the initial data analysis foundation for the AI-Artisans/bda_cs41s1 repository by setting up the Bank Marketing Data Project. She created a structured SQL artifact for the bank_marketing dataset and developed a CRISP-DM Excel artifact to guide subsequent data analysis and machine learning experimentation. Her work emphasized data engineering and database management, focusing on maintaining data integrity through targeted artifact cleanup and removal of obsolete files. By applying disciplined version control and clear commit practices, Maria ensured repository hygiene and traceability. The scope of work was foundational, addressing both the technical setup and ongoing governance of project data.
