Built automated trigger-based ingestion workflows for structured and semi-structured data (CSV, JSON, Parquet, Avro) using ADF, Event Grid, and REST connectors. Migrated legacy SQL Server and Oracle databases to Azure SQL DB and Synapse Analytics using self-hosted and SSIS Integration Runtimes with PolyBase for high-speed loading.Developed a scalable Delta Lake architecture in Databricks with ACID transactions, time travel, and schema evolution for big data reliability. Created reusable PySpark notebooks (Python 3.11, pandas, NumPy, PyArrow) for cleaning, transforming, aggregating, and machine learning modeling via MLlib.Implemented real-time streaming pipelines with Azure Event Hubs, Azure Stream Analytics, and Apache Kafka for sub-second analytics. Designed advanced Power BI semantic models with composite models, dual-mode storage, field parameters, and RLS for performance and governance. Built interactive Power BI dashboards with custom visuals, slicers, drill-downs, bookmarks, and storytelling for enhanced user engagement. Established a Data Quality and Validation framework using Python and Great Expectations integrated with ADF monitoring for proactive alerts. Developed a complete CI/CD solution using Azure DevOps YAML, ARM/Bicep, and GitHub Actions to automate deployment of data and analytics assets.
