About

BBA graduate and aspiring Data Analyst. I've cleaned 20,000+ rows of live sales data, built dashboards that cut reporting time by two-thirds, and helped lift conversions by double digits through the insights I found. My BBA gave me a business-first way of approaching data — I don't just build a dashboard, I think about what decision it needs to support. On the technical side, I work in Excel (Power Query, Pivot Tables), SQL, and Power BI, and I'm currently extending that into Python. During my internship at CollegeDekho, I cleaned 20,000+ rows of sales data using Power Query and Pivot Tables, cutting manual reconciliation time by 40% and enabling daily admissions tracking. I automated the weekly Sales Performance Dashboard, taking reporting turnaround from 3 days down to 1. Digging into regional numbers, I found an 18-22% admissions variation between regions — insight that helped sales leadership reallocate effort and lift conversions by 12%. I also worked with the sales team to streamline CRM lead-tracking, cutting data entry errors by 25%. Since then, I've kept building: dashboards for workshop performance, retail sales, and pizza sales analysis (SQL + Power BI) which are showcased on my GitHub profile - https://github.com/ Preksha-2003.
