Work Experience

Senior Data Scientist - Exl

As a Senior Data Scientist, I architected advanced pricing optimization strategies using decision trees, neural networks, and regression models, enhancing model precision by 12% with XGBoost and streamlining data warehousing performance tracking by 30%. By reducing SMAPE to 26.8 through strategic clustering, data manipulation, and comprehensive exploratory data analysis (EDA)—including feature importance, covariance matrices, collinearity tests, and VIF scores—I delivered more accurate price optimization solutions. Additionally, I automated the pricing process for a fashion retail client, leveraging predictive modeling for seasonality, market trends, and product attributes, which eliminated manual updates and reduced operational efforts by 40%.

Data Scientist - Uber

At Uber, I devised a strategy utilizing the TF-IDF Natural Language Processing (NLP) algorithm to compare restaurant pricing on Uber-Eats against competitors, identifying 45% of listings with discrepancies exceeding 20%. I also leveraged NLP algorithms to analyze user feedback, leading to an enhancement of the Net Promoter Score (NPS) by an average of 0.7 points across multiple geographies through the identification and application of strategic insights. Additionally, I predicted driver demand using time series forecasting, which optimized driver allocation efficiency by 15% and increased customer satisfaction by 20% through accurate demand predictions in specific regions and new geographies.
