What I'm looking for

I’m looking to build reliable, scalable Azure data platforms with governance and automation at the core—owning ingestion, transformations, and orchestration while collaborating to drive measurable data quality and fewer pipeline failures.

I’m an Azure Data Engineer with 5 years of IT Data Engineer experience, focused on data ingestion and transformation for scalable analytics platforms. I build full and incremental data pipelines using Azure Synapse Analytics and parameterize them for Medallion Architecture (Bronze → Silver → Gold), so teams can make data-driven decisions.

I develop complex transformation solutions with PySpark in Azure Databricks, including SCD Type 2 for dimensional models. I also implement governance with Databricks Unity Catalog (RLS and OLS), automate ingestion frameworks, and improve reliability through SIT/UAT, deployment documentation, and root-cause analysis.
