Freelancer profile translated to English.

Description

I am a Senior Java Engineer with over 15 years of experience in developing robust and production-critical backend systems.

I assist companies in the design, development, and operation of reliable, scalable, and maintainable Java / Spring applications.

My expertise covers the entire software lifecycle: from technical design to deployment and production support. I work in cloud-native environments with Docker, Kubernetes, and CI/CD pipelines (Jenkins, GitLab), with a strong emphasis on automation and quality.

Accustomed to enterprise and data-driven contexts, I work with high standards of software quality (automated tests, Cucumber), database management (Liquibase), and architectural best practices (clean architecture, SOLID).

Autonomous and results-oriented, I integrate easily into existing teams, including in international contexts, and I deliver pragmatic solutions adapted to your needs.
