At Amity University Haryana, I’m pursuing an M.Sc. in Data Science, after completing a B.Sc. (Hons) in Physics at Gargi College, University of Delhi. My first-year CGPA was 9.69.

For my Blinkit Sales Dashboard project, I built an interactive Power BI dashboard with DAX measures and calculated columns to explore product categories, outlet performance, revenue trends, and top-performing SKUs.

As a Summer Intern at Ram Lal Anand College, University of Delhi, I worked on classifying tumour and normal samples from the TCGA LUAD dataset. I also completed a Nanoscience research internship at KR Manglam University, Sohna, and currently volunteer with Prayan Foundation.
