Mexico

Message

At BANREGIO / HEY BANCO, I developed and maintained features across Java and Spring Boot microservices behind Toolbox, an internal platform of process-automation tools. I also removed a legacy user type from the customer login flow and validated the change across Android and iOS test matrices.

I created a new tool and optimized existing ones, including automating usage reports with Spring Boot, Java Swing, and JasperReports. That reduced report generation time from about 30 minutes to about four.

Earlier, I developed features for a production transaction-monitoring application at ONECARD and contributed to internal applications at UNIVERSIDAD DE MONTEMORELOS. I’m a B.S. in Computer Systems Engineering graduate from Universidad de Montemorelos.
