At STI Data and Business Intelligence, I integrated data from different sources and participated in designing and building Data Warehouses for analysis. I developed and maintained ETL processes using SQL Server, SSIS, and Azure Data Factory.
I also created Azure Data Factory pipelines, configured connections, monitored runs, and addressed errors. I developed and used OLAP cubes and built Power BI dashboards and reports from processed data.
At Dirección General de Contrataciones Públicas, I administer Microsoft SQL Server databases and develop SQL processes for data loads, migrations, and reporting. By optimizing SQL Server queries, I reduced response times by nearly 50%.
