Generated $55 million extra closing volume in the first 4 months of implementation. Worked on building an ML model to predict the best leads to deliver at a given moment.

Solely initiated and completed 2 ML model cycles for evaluating and predicting customers’ engagement. Worked with lending data from 10+ data sources and built executable functions for data processing in Python/R. Created workflows in Jenkins; ran batch testing in the local Java environment to ensure compatibility with the PROD environment. Saved ~$20k/month on lead costs and increased loan conversion rate by 7% using ML models to optimize lead-processing strategies.
