At Banco de Occidente, I design and maintain ETL/ELT pipelines on AWS for Risk and Deposits data, including regulatory reporting to Colombia's Financial Superintendence. I migrated ETL processes from Pandas to Polars, reducing execution time by 20%.
At Banco Unión, I designed and implemented Pentaho ETL pipelines to consolidate operational data, and analyzed incidents with SQL. I also built SLA tracking reports and metrics that achieved 100% SLA compliance.
In my Marketplace Data Warehouse project, I built an end-to-end ELT pipeline using a Bronze-to-Silver-to-Gold medallion architecture, dbt, and Dagster Cloud. I also created a Power BI analysis of Pokémon data, covering data cleaning, exploration, and segmentation.
