About

I am Ezequias Vaz, a Full Stack Developer specializing in Java (Spring Boot/Quarkus) and Angular, delivering secure, enterprise web applications in regulated environments such as financial services. I am hands-on across backend and frontend, with a focus on building robust REST APIs and reliable data integration with Oracle and PostgreSQL databases. I value maintainability, security, and collaboration with cross-functional teams in Agile environments.

I emphasize clean architecture, code quality, and strong testing practices, aligning with SonarQube quality gates and aiming for high test coverage. I also contribute to CI/CD and automated deployments in OpenShift environments, and I enjoy driving secure-by-default practices and effective teamwork across disciplines.
