Message

At Sherwin Williams, I support and maintain Angular and Java applications, and develop Spring Boot microservices. I’ve also worked with Kafka to build scalable, failure-resilient systems and used GraphQL to design APIs around client data needs.

Earlier, at Ericsson, I developed catalog management functionality with Java, Spring Boot, JPA, and REST APIs. At Kuehne Nagel, I developed a Java application that processed customs shipment addenda through JAXB and a REST API; at Grupo Financiero Inbursa, I reviewed architectural standards and managed a team of Java developers.
