Background
About Catalin S.
I am a dedicated and detail-oriented professional with hands-on experience in SQL Server and Azure SQL Database for designing normalized data models, writing efficient SQL queries, and implementing complex logic using CTEs, views, and stored procedures. I have strong practical knowledge of DDL/DML operations, window functions, and query optimization. I specialize in ETL and data integration, using Azure Data Factory (ADF) to automate the migration and transformation of data from sources such as Excel and CSV into cloud-based databases. In the field of Business Intelligence, I create dynamic Power BI dashboards, develop data models using Power Query, and perform in-depth analytics using DAX to deliver actionable insights. My technical expertise enables me to turn raw data into clear, impactful solutions that support business decisions and drive process efficiency.
