What I'm looking for

I’m seeking entry-level roles in Data Analytics or Business Intelligence where I can build KPI-driven dashboards, strengthen data cleaning and preprocessing, and help teams make faster, data-driven decisions.

I’m a Computer Science undergraduate at BIT Mesra with hands-on experience in data analytics and business intelligence, and I’ve built end-to-end Power BI dashboards. I’m proficient in Python and SQL, with a strong foundation in data cleaning, KPI reporting, and data visualization.

In my data preprocessing and analytics internship at Tata Motors, I supported the end-to-end workflow—data ingestion, processing, evaluation, and reporting—while reducing manual processing time by 30%. I performed end-to-end preprocessing on 50,000+ satellite image samples and cleaned large-scale datasets to support GIS-based smart mobility analytics, improving downstream accuracy by approximately 25%, and I collaborated cross-functionally to integrate outputs into analytics applications.
