Tools and Languages:Java, Microservices, Spring, Rabbitmq, Hexagonal and Clean architecture, Unit test, MongoDB, OracleDB, Docker, Jira, Postman, Git, MockoonSecond Project:Learned GO and writed a microservice that establishes communication using the MQTT protocol between devices, processes the received data using GO routines, and sends the data to another microservice using the AMQP protocol.First Project:My role involves maintaining Java-based applications with a strong focus on performance optimization. I use the SPRING framework to implement various components and functionalities. The application follows hexagonal architecture and clean code principles, and I actively participate in its creation and maintenance.I develop unit tests using the Mockito and JUnit frameworks, as well as integration tests using POSTMAN. The application relies on a POSTGRES relational database for data storage. Additionally, I provide support to the QA team during testing activities and collaborate with the Front-end team on integration tasks.I work in an agile development environment, using SCRUM and KANBAN methodologies, and manage the project tasks using JIRA. I have experience with containerization using DOCKER to deploy and manage the application. I use S3 for storage and retrieval of data or files. Monitoring and analyzing the application's performance are also part of my responsibilities.

I had maintained both Monolith and Microservices applications using Java and Kotlin, ensuring their smooth operation in the production environment. I had made extensive use of the SPRING framework, including modules like Spring Boot, Spring Cloud, Spring Data, Spring MVC, Spring Security, and Spring WebFlux.Certain components or services had been developed and implemented using the PLAY framework. I had been responsible for creating unit tests with Mockito and JUnit, as well as integration tests using tools like POSTMAN. I had also created end-to-end (E2E) tests to ensure system functionality.I had worked with both relational databases (such as POSTGRES) and non-relational databases (such as MONGO), depending on the specific requirements of each service. I had provided support to the QA team during testing activities and had collaborated with the Front-end team to ensure seamless integrations.I had followed agile methodologies, including SCRUM and KANBAN, and had efficiently managed project tasks and feature development using JIRA. To facilitate deployment and scalability of microservices, I had leveraged DOCKER for containerization.Participated in the development and maintenance of the Justa Account, a comprehensive financial system that helped more than 10,000 establishments in Brazil receive, pay, and manage money.

I had been developing Java applications, with a strong focus on backend development. I had worked with relational databases to store and manage data efficiently. Git had been my choice as a version control system to manage and track code changes.I had followed an Agile methodology to ensure efficient development processes and timely delivery of features. Collaborating with cross-functional teams, I had gathered requirements and implemented solutions. I had strived to write clean, maintainable, and efficient code to meet project objectives.Conducting code reviews had been a regular part of my role, and I had provided feedback to team members to improve code quality. I had actively participated in agile ceremonies such as stand-ups, sprint planning, and retrospectives. Troubleshooting and debugging issues had also been a key aspect of my responsibilities to ensure smooth application functionality.
