Description

Senior Backend Java Developer – 9 years of experience

Specializing in backend Java development with Spring Boot and REST APIs, I am involved in the design and implementation of robust and maintainable application services.

My experience covers:

Development of backend services and distributed architectures
Participation in technical choices and solution design
Integration via JMS, Apache Camel, IBM MQ
Implementation of unit tests (JUnit, Mockito)
Industrialization and CI/CD pipelines
Performance optimization and code quality

Accustomed to demanding environments, I favor clear architectures, maintainability, and system reliability.

I regularly work on existing codebases to analyze, correct, and improve Java backend applications, while ensuring the stability and quality of services.

Available for both design projects and missions for evolutionary maintenance, bug fixing, optimization, or improvement of existing code.
