PROFILE
Valeria-oliva
Valeria Oliva developed and delivered seven features over three months in the pcamarillor/O2025_ESI3914B repository, focusing on data engineering, analytics, and onboarding documentation. She built end-to-end data pipelines using PySpark and Spark SQL, including a Spotify artist collaboration workflow that ingests CSV data, transforms it into graph structures, and writes to Neo4j for analysis. Valeria also created Jupyter Notebooks for educational labs, demonstrating object-oriented programming and structured streaming with real-time log processing. Her work emphasized reproducibility, modularity, and onboarding efficiency, with well-documented code and utilities in Python and SQL, supporting both business value and maintainable engineering practices.
