What I'm looking for

I'm seeking a Data Engineering or Analytics Engineering internship where I can build reliable data systems and continue growing as an engineer.

I'm studying Data Science at ITBA and building practical data systems through ETL, database, and data warehouse projects.

I designed a modular retail sales ETL pipeline in Python and Pandas, with ingestion, cleaning, transformation, validation, and persistence stages. I added fail-fast data-quality checks, generated temporal features for reporting, and exported curated datasets in Parquet format.

I’ve also designed conceptual, logical, and physical models for transactional relational databases in SQL Server. My work includes stored procedures, triggers, constraints, business rules, realistic sample data, and testing.

For analytics, I designed a star-schema dimensional model with fact and dimension tables and connected it to Power BI. I’m seeking a Data Engineering or Analytics Engineering internship where I can build reliable data systems and continue growing as an engineer.
