What I'm looking for

I seek senior engineering roles where I can design and maintain scalable cloud-native systems, work in agile teams, and drive architectural improvements and reliability.

I am a Senior Full Stack Developer with over fifteen years of experience in Java development, cloud platforms, and full-stack architecture for large-scale systems. I have contributed to major projects at SERPRO, Motion Industries, Contabilizei, Stefanini (Ford), and Stere, delivering resilient microservices and platform solutions.

My work spans cloud and on-premises environments—AWS (Cloud Practitioner), GCP, Kubernetes, Docker, OpenStack—and a broad backend and frontend stack including Java, Spring Boot, Kotlin, Angular, REST APIs, and database technologies such as PostgreSQL, Oracle, MySQL, and MSSQL. I focus on clean architecture, refactoring monoliths to hexagonal designs, and maintaining high reliability in supply-chain and payroll systems.

I bring practical experience with CI/CD, testing (JUnit, Mockito), security (encryption, JWT, authentication), and developer productivity on Linux. I value agile practices, clear documentation, and collaborative teams that deliver scalable, maintainable software for real-world business impact.
