What I'm looking for

I want to build and optimize reusable Azure Data Factory ETL pipelines, improve performance through automation and monitoring, and collaborate with stakeholders to deliver accurate, reliable BI-ready data.

I’m a data solutions developer with 12+ years designing, building, and optimizing ETL pipelines and data warehouse-focused systems. I specialize in Business Intelligence skills like SQL, data pipelines, and cloud-based data systems, with deep expertise in Azure Data Factory.

At TCS, I developed and maintained automated data pipelines from structured and unstructured sources to Azure Blob Storage, building reusable pipelines that reduced development timelines by 25%. I implemented automatic error alerting with customized mail on error mechanisms, cutting manual effort and time by 50% while improving monitoring, troubleshooting, and stakeholder alignment.
