At ACI Worldwide, I led the design and delivery of a greenfield Databricks Lakehouse, bringing Jira Cloud and on-premise Oracle data into a governed cloud architecture. I built metadata-driven ingestion frameworks, production pipelines and dimensional models for analytics.
I developed and optimized 20+ PySpark and Spark SQL pipelines, and architected a Bronze/Silver/Gold Lakehouse on Delta Lake with Unity Catalog governance. Publishing curated datasets improved data accessibility and reporting efficiency by ~40%.
At K2View, I delivered 25+ technical demos of the Data Product Platform and built prototypes that reduced proof-of-concept timelines by 40%. I also designed RAG pipelines, cloud migration accelerators and synthetic data generation frameworks.
At Tata Consultancy Services, I migrated 200+ ETL pipelines from GCP to Azure Databricks, improving performance and reducing infrastructure costs. I also reworked orchestration and tuned Spark SQL to reduce pipeline failures by 60% and runtimes by up to 70%.
