Work Experience

Data Analyst

Larc Software | Client: Capgemini

Jul 2024 - Present

Investigated a fall in the 90-day repeat purchase rate from 24.8% to 21.7% by analyzing 1 lakh+ orders across 11 tables in MySQL. Sized the drop at 451 lost repeat customers and ₹6.8 lakh in gross margin. Built a clean SQL layer without touching production data. Merged 1,167 duplicate customer emails, which uncovered 239 repeat buyers hidden across two accounts. Standardized 8,101 inconsistent order statuses and removed 5,175 fully refunded orders from the KPI. Tested leadership theories with cohort analysis. Showed that the rise in Instagram-acquired customers explained only 0.4 of the 3.1-point drop. Found late first deliveries to be a key driver: their share doubled from 12% to 26%, and those customers returned at 12–15%, against 25–26% when the first order arrived on time. Quantified a courier cost trade-off. Switching to a cheaper courier saved ₹1.3 lakh in shipping on East and North-East routes but cost ₹1.7 lakh in lost repeat-order margin, so the switch lost money overall.

Junior Data Analyst

Larc Software | Client: Capgemini

Apr 2023 - Jun 2024

Analyzed 800 financial transactions across 189 accounts and 180 customers covering January 2023–June 2024 to evaluate transaction behavior, account activity, and potential financial risk indicators. Identified data-quality issues, including non-unique transaction IDs, negative transaction amounts, and negative balances, distinguishing data anomalies from potentially meaningful financial signals. Developed Power BI dashboards to monitor account balances, transaction activity, overdrafts, and financial risk indicators, enabling stakeholders to identify accounts requiring further investigation. Developed account-level activity classifications and balance segments to assess transaction patterns and support structured customer financial analysis. Evaluated four risk indicators-overdrafts, large withdrawals, balance volatility, and high-risk scores- to identify accounts requiring further investigation. Flagged seven accounts triggering three of the four risk indicators and recommended manual review to support risk assessment and follow-up. Performed a one-sided t-test to evaluate whether accounts with higher transaction volumes maintained higher balances, obtaining a borderline statistically significant result (p ≈ 0.04). Documented analytical assumptions, data limitations, and recommended actions, including monitoring unusual balance fluctuations and reviewing overdraft cases.
