Here has been my place for the last 10 years. I started the project from zero, and in less than 4 months, we had the first client.We always use Java in this project (we started using Java 7, passed to Java 8, Java 11, Java 16, and now Java 17), but we changed the frameworks a lot. We started using JSF, richfaces, primefaces, JBoss, EJB, JPA, Selenium, Hibernate, and the MySQL database.After, we change all frontend from richfaces to primefaces and the application server from JBoss to wildfly. The database was the same, I needed to change from Mysql to MariaDB. All this change was because the support of the technologies finished or started to be paid.The project became a big monolith system, and I needed to do something. This time, I started to study microservice and started to use frameworks and technologies like spring boot, spring batch, maven, swagger, docker, Kubernetes, API gateway, discovery, consul, config server, git, GitLab, rabbitMQ, AWS SQS, AWS S3, Jenkins, grafana, hibernate, JPA, load balance, retry, keycloak for security and others new technologies.

Here I made a project that I'm very proud of because the project reduced the time spent creating a company, from days to minutes, which helped entrepreneurs and the country's economy.* Develop a web service SOAP to integrate with a PHP frontend* Develop an intern CRM in Java and using frameworks like Struts, Jasper Report, Hibernate, JPA, and database Oracle* Development of a project called FCN/REMP, which I was responsible for. The development was based using Java and JSF, richfaces, EJB, JPA, and database Oracle. More than that, this project communicated using the web service SOAP with others internal and external projects necessary to validate data to create a new company in the state of Minas Gerais and after, to many other states

That was my first full-time job and I learned a lot here.* Development of a full stack project, connecting a front and back end to a BI project that used to sell gas. For this project, we use Java with JSF, JBoss Seam, EJB, Hibernate, and JPA. SOAP protocol for the communication between projects and Oracle database.

Here I start my career and where I have my first contact with Java in a private company. I enjoyed so much my internship there. I learned and developed a lot of my professional skills and developed so much on how to be a great professional.* Development of a frontend in OpenLaszlo, to communicate with a web API that was developed in Java, using the MVC Mentawai framework with hibernate accessing database Postgres and SQL server.
