Intermediate Python programming, APIs, exploratory data analysis, statistical modeling, machine learning foundations, and collaborative software development.
About
DS 2500 focused on intermediate Python programming for data science, object-oriented design, working with APIs, cleaning messy real-world datasets, building visualizations, and introducing machine learning fundamentals within a collaborative software engineering workflow.
The semester culminated in a team research project analyzing consumer banking complaints using live CFPB data. We collected roughly 35,000 records through the CFPB API, explored complaint patterns across major institutions, and evaluated whether regulatory enforcement actions appear to change harmful consumer outcomes, my first complete end-to-end data science pipeline.
Skills
Featured Project
Do Regulatory Penalties Change Bank Behavior?
Using roughly 35,000 CFPB consumer complaints collected through the CFPB API, our team investigated whether major enforcement actions against large banks appear to reduce harmful consumer complaint patterns. The project combined API-based data collection, exploratory analysis, visualization, and statistical comparisons across multiple financial institutions.

DS 2500 significantly strengthened my programming abilities beyond introductory Python. I learned to work with real-world APIs, clean messy datasets that never arrive in tidy CSV form, and build reproducible analysis pipelines my teammates could trust. Creating professional visualizations and communicating technical findings through written reports and presentations became as important as writing the code itself.
The CFPB banking project was my first complete end-to-end data science workflow, from API collection through exploratory analysis to a defended conclusion. Collaborating with Git, dividing analytical responsibilities, and integrating our work into a single narrative taught me how data science actually happens in teams. That foundation directly prepared me for future machine learning and analytics coursework, where rigor, reproducibility, and clear communication are non-negotiable.
