## About

```text
At KPMG Global Services, I improved an existing churn prediction model through machine learning experimentation, feature engineering, hyperparameter optimization, and K-fold cross-validation. The work increased recall from 62% to 71%.

At Accenture, I developed predictive models for vehicle brand recommendations and lead conversion, and implemented a daily lead-scoring and alert mechanism that increased lead conversion by 11%. I also developed an enhanced lead profiling system using SQL and Google Cloud Scheduler.
