Utkarsh Shrivastava

Data engineer with 3+ years building production data systems for one of India's largest survey research organizations (BARC India), processing data from 6,000+ households monthly. I specialize in Python automation, ETL pipeline design, and statistical sampling — including a dynamic sampling algorithm that cut processing time from 2 days to 2 minutes, and a RIM weighting engine still in production after 3 years. Background in IISER (biology, BS-MS) plus an ongoing MSc in Data Science. I build reliable, well-documented systems and enjoy solving problems that don't have off-the-shelf solutions.
