Reduced the time of a specific mass calculation scheduled algorithm from 48 hours to 1 and a half hours.• Mass test generator: Acquiring production contracts and converting all sensitive data to random data, then transferring them to the development environment, allowing tests on real contracts as if they were fake. After deployment in production, reduced the time to make a mass of tests from 3 weeks to 1 day.• Language parser: A .NET application tasked with reading VisualAge for Java ESF files to extract all business logic and writing it into Java classes, enabling the conversion of large programs in a matter of minutes, instead of weeks.
