Message

At Tata Consulting Services, I develop ETL pipelines that bring data from other systems into GCP, including integrations with REST APIs and MongoDB. For the MetLife project, I also developed data flows with Dataform and Dataflow, transformed data with SQL and DBT, and created Power BI dashboards.

Across projects including PepsiCo, Walmart, and Social Medical Data, I’ve worked on cloud migrations, prediction models, and data pipelines for analytics and reporting. Earlier, I managed IT and application development work, and at Infinity Code Solution I provided technical advice on data processing and modeling and created social impact indicators for non-profit organizations.
