What I'm looking for

I’m looking for a role where I can modernize and maintain mission-critical Java backend systems, focusing on stability, clean code, automated testing, and reliable operations—collaborating in Scrum/Agile with strong ownership and continuous improvement.

I’m a Computer Engineer and Senior Java Backend Developer with over 13 years of experience designing, developing, maintaining, and modernizing enterprise systems across public and private sectors. I specialize in Java (JDK 7–22), Spring/Spring Boot, JPA/Hibernate, relational databases, and SOAP/REST services, with a strong emphasis on stability, code quality, automated testing, and operational continuity.

In production-critical environments, I’ve handled maintenance and evolution of backend applications (e.g., Java 11) and led improvements through unit testing with JUnit/Mockito. I’ve also supported incident resolution and corrective/evolutionary maintenance involving Oracle and MySQL, managing version control with Git.

My background includes building and integrating Spring Boot services with Spring JPA, Spring JMS, and ActiveMQ, plus implementing SOAP and REST web services for system integration. I’ve worked with JSF/PrimeFaces and Spring ORM/Hibernate, optimized SQL queries and stored procedures in SQL Server and Oracle, developed electronic invoicing systems (JDK 1.7, JDBC, JasperReports), and served as a technical leader for a team of 3—continuously evolving legacy systems toward modern, reliable solutions.
