The company has a need to migrate Oracle EBS from version 12.0.6 to version 12.2.4. The migration was carried out in steps and by groups of portals (satellite systems to EBS).
I received a group of portals as an assignment to which I performed a detailed analysis to detect the portions of code where the connections to EBS are made.
Each portal has a different architecture and framework, from Struts to JSF. Some have their own database schema, others go straight to EBS. Because each one handles a different structure, the solutions to the requirement were diverse.
I am in charge of analyzing, proposing a solution, documenting and sending it for review with the architect of the area. When the architect validates, we proceed with the Development, testing and production of the change made.

Currently I am also working with the JHipster framework that allows to speed up application development times. Build an architecture with Spring Boot, Maven, JUnit, Liquibase, Bootstrap, Angular, Typescript, Browsersync among others. These applications are deployed on AWS using Elastic Beanstalk.
