Allocated in an team that was responsible for the supply and logistics management of all distribution centers, he worked as a Senior Java developer on the migration of a Goods Receipt System, with Java EE2 implementation, modularized in dependencies with Maven Repository, using PrimeFaces (JSF) as a screen, WebLogic as a server, Oracle as a database. He also helped in the creation of new modules in a Basic Registration Management project used by the entire company, using good practices of clean code, high cohesion, and low coupling where he also had the opportunity to lead a team of junior developers that helped him implement this project.

• Agile methodology as support, planning, and daily, refinement meetings, and retro to evaluate where to improve
• As a Java developer, he coded the system implementation, using good development practices, low coupling, and high cohesion.
• Code quality, the system was built creating unit tests and integration to ensure excellence and accuracy
