PROFILE
Luis Santana
Over a three-month period, contributed to the pcamarillor/O2025_ESI3914B repository by developing six features focused on data engineering, analytics, and operational monitoring. Delivered Python modules and Jupyter notebooks for playlist analysis, a finance-oriented BankAccount class, and Spark-based data processing labs supporting schema generation, cleaning, and export to Parquet and CSV. Implemented a Neo4j ingestion pipeline for product reviews and a real-time structured streaming demo for server log analysis, enabling near real-time insights and graph-based analytics. Leveraged technologies including Python, Apache Spark, Pandas, and Neo4j, with an emphasis on scalable data pipelines, documentation, and onboarding support throughout.

Sep 1, 2025In Sep 2025, the pcamarillor/O2025_ESI3914B project delivered two major capabilities that enhance both finance-oriented prototyping and scalable data workflows, driving faster insights and safer software. The Bank Account Manager module provides a user-facing Python library and a Jupyter notebook implementing a BankAccount class with deposit, withdraw, and balance operations, including input validation and error handling to reduce misuse and support rapid feature prototyping for financial workflows. The Spark Data Processing Lab integrates Spark-based utilities and notebooks for schema generation, data cleaning/transformation, lazy evaluation optimization, unions/joins, and data export to Parquet/CSV, enabling scalable data pipelines and easier downstream consumption by BI tools. Together, these efforts improve data reliability, developer velocity, and BI readiness across the stack.
