I am part of the Microsoft Ads vertical. I build scalable Data Science-based solutions to enhance new and existing products for Microsoft.

At PwC US, I have worked as a Data Science Associate. I was part of the US Healthcare domain where I have worked on multiple Data Science projects to provide our clients a better solution. Some of the interesting projects that I have worked on are:Insomnia Cause Identification: I have worked on building a Classification model to identify the most important features of an Insomnia patient for a large pharma company. In this project I have tried different ML models such as Logistic Regression, Decision Tree, Random Forest, and XGboost. Also, I have created a scenario-based patient profile using the output parameters of the ML models.CHF Patient Prediction: This is another Classification-based project where my goal was to predict CHF patients based on a range of unique features. I have used different EDA techniques such SMOTE, missing value imputation by using KNN etc. For modelling, I have used Logistic Regression, Decision Tree, LighGBM etc models.
