What I'm looking for

I’m looking for a Java-focused role building and maintaining web applications in agile teams, where I can ship features, integrate APIs, and strengthen data handling with Spring Boot and SQL.

I’m a Computer Science bachelor and experienced web developer. I’ve worked as a Java, JSF, and Spring boot developer in agile environments, increasing features in a tax web application while using tools like git, jira, maven, and automation workflows.

I designed and coded a web application for the Angolan Sportive Fishing Federation with Asp.Net, C#, and SqlServer to support championship management and registries. More recently, I maintained and evolved a finance ministry web application (Java 8, jsf/Bootstrap), built SQL scripts (Oracle), consumed REST services, and produced reports with Cristalreport.
