I build scalable AWS data platforms, ETL pipelines, and analytics solutions that reduce processing cost and time.

I've built enterprise data platforms for Tata Technologies, IBM, Wipro, and Aloha Technology, delivering AWS-based ETL, analytics, migration, and data quality solutions across manufacturing, finance, telecommunications, and pharmaceutical domains.

At Tata Technologies, I lead a centralized MES Control Tower lakehouse on Amazon S3 and Databricks, integrating 22 global business units and 72 plants. I build batch and real-time pipelines with Glue, PySpark, Python, Kafka, and Databricks, while delivering REST-enabled analytics, QuickSight and Power BI dashboards, and a Groq LLM chatbot for Confluence documentation.

At IBM, I architected an automated AWS data-quality and ingestion framework for Barclays that reduced manual troubleshooting and validation effort by 60%. I also optimized Glue jobs and Athena queries to reduce AWS processing costs and execution time by 50%, earning IBM Appreciation and Leadership Appreciation recognition.

Across my work, I focus on reliable data lakes, governed cloud architectures, high-performance SQL and Spark processing, automated monitoring, and practical collaboration with business, QA, MDM, and engineering teams.
