Over a three-month period, contributed to the pcamarillor/O2025_ESI3914B repository by developing nine data engineering features focused on analytics, data cleaning, and scalable processing workflows. Built Jupyter Notebooks in Python and PySpark to process music streaming data, implement banking logic, and transform airline and sensor datasets. Designed reproducible pipelines for extracting, cleaning, and exporting data in Parquet, CSV, and JSON formats. Integrated graph analytics using Neo4j and enabled real-time log analysis with Spark Structured Streaming. Emphasized validation, schema management, and modular code, resulting in reusable workflows that support downstream analytics, reporting, and lab environments without introducing any reported bugs.
October 2025 monthly summary for pcamarillor/O2025_ESI3914B. Delivered two end-to-end data engineering notebooks enabling graph-based analytics and real-time streaming capabilities. Key work includes Lab 06: Neo4j Data Ingestion, Graph Creation, and Verification, and Lab 07: Structured Streaming with Files. Brought forward end-to-end data pipelines: from ingestion to graph-based storage and verification, and from synthetic log generation to real-time streaming processing. No major bugs reported; minor notebook/environment tweaks were performed to improve reproducibility across environments. Impact: Enables reproducible graph analytics on artist/lyrics data and real-time log processing capabilities, accelerating validation and insights, and establishing a reusable blueprint for future labs. Technologies/skills demonstrated: Neo4j, Jupyter Notebooks, Python, Spark (Structured Streaming), SparkSession management, and data generation modules.
