Message

At Compass UOL, I develop and maintain RESTful APIs for enterprise checkout flows and implement backend features for a banking client. I migrated 70+ applications from IBM WebSphere to WildFly, resolving compatibility issues and reducing the client’s application-server cost.

Earlier at Compass UOL, I maintained microservices-based systems and implemented observability and alerting. Across my software development work, I’ve contributed to Java systems, Oracle Commerce projects, and web applications, including integrating Keycloak and helping migrate an Angular application from version 5 to 6.
