What I'm looking for

I’m looking for a team where I can build and evolve Java/Spring microservices, own production REST APIs and JasperReports, and work in Scrum with JIRA—collaborating closely to improve reliability and grow my DevOps and backend expertise.

I’m a Software Engineer with a degree in Computer Engineering from UNISAL (2023) and over 4 years in the Java ecosystem. I’ve worked across everything from maintaining legacy systems to building modern microservices with Spring Boot and Quarkus.

In production environments, I’ve contributed to the evolution of enterprise back-end systems (JSF/PrimeFaces), RESTful APIs, and reporting with JasperReports. I’ve also been involved in migrations—transforming a legacy Delphi project into Java 11 with Spring Boot, JWT authentication, and a React front-end.

I work in Scrum using JIRA, collaborate with client-facing teams, and support system reliability through CI/CD practices with Jenkins and AWS. I’m at Prime Results now, continuing development of enterprise Java systems after being hired directly into the internal engineering team.
