About

I am a Data Engineer who loves turning messy data into clear, reliable insights. Over the past 6 years, I’ve moved from automating web data extraction to architecting complex cloud pipelines for global manufacturing leaders. My focus is on efficiency—whether that’s reducing manual work by 40% through Airflow automation or migrating massive IoT datasets from Cosmos DB to SQL warehouses to make them easier to analyze. I believe that clean code and a "Single Source of Truth" are the foundations of any successful data strategy. What I bring to the table: * Data Architecture: Expert in Star and Snowflake schemas. * Tech Stack: Heavy focus on Python, PySpark, SQL, and Azure. * Domain Knowledge: Specialized in Manufacturing IoT and OEE metrics.
