I build reliable data pipelines and improve operations through ETL, analytics, and process optimization.
IndiaWhat I'm looking for
I've delivered data and process improvements at Cognizant Technology Solutions, building ETL solutions that bridged Mainframe and on-premises systems while meeting customer requirements.
As a Programmer Analyst, I developed and maintained 100+ Unix scripts to automate 30 ETL pipelines, orchestrated delivery to Hadoop servers using Maestro and Autosys, and improved data-processing speed by 30%. I also managed enhancements across 12+ applications with cross-functional teams.
During my Kellanova internship, I analyzed distribution models across five points, contributing to a 20% increase in inventory turnover, and trained sales teams on CRM platforms to reduce order turnaround time by 10%.
I've also built a Python and React.js UI platform at High Radius and developed a RAG-based LLM in KNIME for HR query resolution. I'm pursuing an International Master in Business at SDA Bocconi Asia Center and bring Lean Six Sigma and operations-focused training to data-driven work.
