What I'm looking for

I seek a cloud-focused data engineering role where I can design scalable ETL/ELT pipelines, optimize Spark workloads, apply Delta Lake governance, and deliver analytics solutions within an Agile, collaborative team.

I am an Azure Data Engineer with 7+ years of experience delivering cloud data engineering, MSBI, and data migration solutions across enterprise environments. I design and implement scalable ETL/ELT pipelines using Azure Data Factory, Azure Databricks, Snowflake, ADLS and Delta Lake to provide curated datasets for analytics.

My accomplishments include migrating data from SQL Server to Snowflake across Dev/QA/Prod, optimizing Spark and Delta Lake performance using partitioning, broadcast joins and Z-Order, and implementing Unity Catalog for governance. I automate orchestration with ADF triggers, Databricks Jobs and Azure Logic Apps while managing CI/CD and version control via Azure DevOps.

I build business-facing analytics by integrating processed data into Power BI and Qlik Cloud dashboards, implement row-level security and robust data models, and follow Agile practices to deliver reliable, performant data solutions that enable actionable insights.
