What I'm looking for

I seek roles where I can build scalable data pipelines, automate reporting, optimize query performance, collaborate cross-functionally, and grow into technical leadership while delivering measurable business impact.

I am a data analyst with hands-on experience building and deploying data pipelines using PySpark and Sqoop, automating reports with Python, and optimizing large-scale queries on Hadoop, Hive and Impala to drive measurable performance gains. At Cotiviti I automated critical business reports, reduced report generation time by 80%, and improved query runtimes by 30–40% while enabling data-driven decisions across teams.

I have a strong foundation in computer science from NIT Raipur, extensive programming experience in C++ and Python, and a proven problem-solving track record in competitive programming. I take ownership of end-to-end tasks—whether designing ETL flows, troubleshooting performance bottlenecks, or delivering scheduled automation—and thrive on translating complex datasets into actionable business insights.
