At Accenture, I build Azure and GCP data platforms that process 12M+ records daily across 25+ enterprise feeds while maintaining 99.9% SLA reliability.

I've designed Medallion Lakehouse architecture on ADLS Gen2 and Azure Databricks for 50TB+ of corporate data, improving analytics query performance by 40% and reducing cloud storage costs by 25%. I also create Azure Synapse and dbt semantic models powering Power BI dashboards for 300+ users.

I modernize legacy ETL into Python, SQL, and Apache Airflow pipelines, strengthen CI/CD and data governance, and build practical tools such as a Flask and React data-governance ecosystem and compliance automation that cut report generation from four hours to under two minutes.
