During my period of contribution to Bento Tecnologia, I played a crucial role in the development of the ERP system with financial, administrative, user management, control management, etc. modules.I used Java Spring Boot and JPA/Hibernate to develop the backend layer of the system, ensuring a robust and scalable architecture.Managed the PostgreSQL database, implementing migrations for version control and creating custom queries with ELSQL to optimize performance.Developed integrations with other web services, expanding the system's functionalities and promoting an integrated experience for users.Implemented dynamic queries using JPASpecification, providing flexibility and efficiency in data retrieval.I adopted REST standards to guarantee the interoperability and scalability of the system, facilitating communication between different modules and services.Additionally, it contributes to the development of the frontend using Angular, ensuring a consistent and intuitive user experience.I also highlight my expertise in creating personalized queries for generating reports, using Jasper Reports technology. This ability allowed the system to provide detailed and personalized reports, meeting the specific needs of users and the company.My work at Bento Tecnologia was marked by the ability to employ a wide range of technologies and frameworks, always changing the delivery of high-quality solutions adapted to the requirements of the project and clients.

During my work at the Department of Industry and Commerce of the state of Goiás, I actively participated in the development and maintenance of ERP systems, with a focus on tax incentive projects. Below are the main aspects of my work:Contributed to the development and maintenance of ERP systems in Java with Spring Boot, adopting a microservices architecture to support the Secretariat's tax incentive projects.I worked on several ERP modules, including Financial, Reporting for reporting, Authentication, Administrative and Customer (for external access to the government).I used PostgreSQL and MySQL as DBMSs in different projects, applying Spring Data JPA with Specifications and other tools to ensure data efficiency and integrity.Containerized some applications using Docker, simplifying the deployment and maintenance processes.Implemented unit and integration tests using JUnit 5, Mockito and RSpec, ensuring the quality and stability of services developed in both the backend.On the frontend, I worked with Angular 13 with TypeScript, employing Vue.js in some cases for more dynamic and interactive interfaces.I developed graphical interfaces using Angular Material and Vue.js, and when necessary, I used HTML5 and CSS3 for additional customizations.I developed access validations based on authentication and permissions, generic and reusable criteria, reactive forms and state generation with NGXS on the frontend.In addition to developing the ERP, I participated in parallel projects using Groovy on Grails and Ruby on Rails, integrating them into the main system of the Department of Commerce.My performance was characterized by emotions and commitment to delivering high-quality solutions, adapted to the specific needs of the Secretariat and contributing to the strengthening of industry, commerce and services in Goiás.
