Professional Experience

Quantitative Analyst

Hannover Reinsurance Company LLC 2019 - Present
  • 2025: Developed an automated machine learning solution that forecasts Net Amount at Risk for every insurance coverage reported by Ceding Companies. This solution substantially reduced the manual analysis required by approximately half of our workforce working on this analysis.
  • 2024-2025: Developed a solution that integrates automation and machine learning techniques (classification modeling) for the Company's Board of Directors. This solution resulted in substantial improvements in accuracy and consistency and was recognized by The Chief Executive Officer as having significant value for the organization from a global perspective.
  • 2024: Developed a solution for the Company's Senior Vice President of Operations that employs an ETL process to import data provided by Ceding Companies on a recurring basis. This data is subsequently reformatted into a usable format, thereby eliminating the necessity for an external consultant to make routine updates to a legacy program.
  • 2024: Developed an automated and scalable solution for the Company's Senior Vice President of Operations, which enables seamless employee interaction with more than 90 individuals.
  • 2023: Developed an automated solution that identifies outliers in the Company's data using statistical analysis. A corresponding management report displays all outliers, and a drill-down report is reviewed daily by several analysts. This solution has detected significant issues before they escalate into problems for downstream users.

Assistant Business Controller

Chicago Pneumatic Company LLC 2012 - 2018
  • In collaboration with internal departments, such as General Management, Human Resources, Sales, and Marketing, I spearheaded the development of automated department reporting dashboards.
