Java Backend Developer at Atlantic Solutions, maintaining corporate systems with complex business rules and Oracle database integrations.
BrazilWhat I'm looking for
At Atlantic Solutions, I develop and maintain corporate web applications using Java, Struts 1.3, JSP, JavaScript, and PL/SQL. My work includes implementing business rules and improving complex workflows.
I create and maintain SQL queries, scripts, procedures, and Oracle integrations, and adjust reports with IReport/JasperReports. I also investigate incidents, fix bugs, and support homologation, testing, and production environments.
I participate in technical and business meetings to understand and refine requirements. I also work on JSP/Struts screens, Java Actions, front-end validations, and AJAX integrations.
I'm continuing to develop my skills in Spring Boot, REST APIs, microservices architecture, testing, and software development best practices. Earlier, at Mercado Livre, I mediated agreements between consumers and sellers using Salesforce and worked in fraud prevention.
