Youse Insurance | Oct 2021 - Jul 2023

Senior Data Scientist

• Implement a new Total Loss pricing definition model. Apply Machine Learning algorithms (LGBM) to improve the conversion of clients in new contracts. This project improves 3% of contract conversions having a Gini parameter greater than the GLM model. • Maintain 5 real time models running in production (AWS Sagemaker) and its reports. • Analyze data from Bureaus to find better metrics that could reduce the risk uncertainty for claims. We analyze 3 bureau datasets, finding 1 feature that could reduce the uncertainty. • Implement A/B test environment, making possible compare elasticity adjusts for products Pricing. • Reduce the impact of loss ratio occurred in insurance market, using data, suggesting price increase or reducing, acting with the Actuarial team. • Implement alternative to score clients in using AWS Endpoints at QA Environment, making possible analyze profiles for market competitiveness. • Improve ETL process using Scala or PySpark.

Cast group | Oct 2018 - Present

Data Scientist

● Led a project to predict network traffic consumption for 3.500 Bank of Brazil branches, by applying ML and AI to avoid service unavailability, thus safeguarding ≈ US$ 1M/hour in revenue per branch. branch. ● Implemented an efficient incident channel to assist internal and external clients of the Bank of Brazil regarding systems issues using the Pytorch Bert Model. This increased productivity and decreased manpower need from 6 to 2 professionals to manage issues. ● Decreased the internal system unavailability by 15%, by employing anomaly detection, Kafka, Python, CI/CD using Jenkins, Argo, and Kubernetes, among other tools, avoiding an estimated profit loss of ≈ US$ 140K/hour due to the unavailability of financial contracts. ● Developed a Spotfire dashboard to demonstrate forecast outcomes the number of incidents for each Bank of Brazil application allowing managers to decide about the workforce distribution for the next week’s operation, thus increasing productivity.
