- Design, build, and maintain robust cloud data pipelines using Azure Data Factory (ADF), Azure Databricks, PySpark, and Spark SQL.
- Implement and manage the Medallion Architecture — moving and transforming data through Bronze (raw/audit), Silver (cleansing/dedup/SCD), and Gold (business aggregates) layers.
- Perform complex data transformations, cleansing, deduplication, and incremental loads using Delta MERGE, supporting both Slowly Changing Dimensions (SCD Type 1 and Type 2).
- Optimize Spark workloads by tuning shuffle partitions, managing memory to prevent OOM errors, and leveraging Adaptive Query Execution (AQE).
- Apply optimized join strategies, including broadcast joins for small datasets and salting techniques to handle data skew.
- Implement robust exception handling,



file dependency validation, and asynchronous batch processing to ensure pipeline reliability.
- Ensure high data quality through schema enforcement, schema evolution handling, and validation against expected target criteria.
- Monitor, troubleshoot, and resolve production job failures by analysing cluster scaling behaviour, Spark UI metrics, and physical query plans.
- Build and maintain CI/CD pipelines for Databricks using Git, Azure DevOps, and Databricks Asset Bundles (DABs), with setting-specific parameterization for Dev, Test, and Prod.
