I am a hands-on Data Platform Lead with a focus on functionality before technology. With my combined skills in Data Architecture, Data Engineering, and Product Ownership, I can help bridge the gap between raw data and valuable insights.
Here are some key skills I bring to the table :
☑️Modern Data Platform architecture : I can organize Data layers, separate concerns and automate ETL/ELT processes.
☑️Data Platform development : I have expertise in ER modeling, Kimball modeling, advanced SQL coding, ETL/ELT automation and performance tuning for Data Warehouses, Data Pipelines and Dashboards.
☑️In terms of hands-on experience : I have worked extensively with Snowflake and the Azure Data Ecosystem, including Azure Data Factory, Azure SQL Database and Power BI.
