The Story

I'm Praveen. I build reliable pipelines for the World Bank's budget data.

I build the pipelines that move financial, budget and HR data out of SAP, REST APIs, SFTP drops and ODBC sources and into the World Bank's new Budget Planning Systems. Before that I migrated 4TB of production data at Infosys without losing a row, built AI automation agents at Goodie Bag, and finished an MS in Data Science at UMass Dartmouth with a 3.97 GPA.

Based in: Washington, DC
Working since: 2020
Studied: MS Data Science, 3.97 GPA
