What I'm looking for

I seek a full-time backend role on a collaborative team where I can build reliable microservices, continue learning, contribute to real projects, and grow professionally.

I am a Java backend developer with more than a decade of professional experience leading projects and teams who transitioned to software development to focus on building reliable backend systems.

I have developed multiple Spring Boot applications and microservices using Docker, MySQL, JWT, Eureka, Redis, and Spring WebFlux, and I prioritize writing clean, maintainable code and automated tests.

My background includes implementing observability and quality tools such as Prometheus, Grafana, SonarQube, and JaCoCo, and I follow TDD/BDD practices, SOLID principles, and clean architecture to deliver robust solutions.

I am looking for a full-time role where I can keep learning, contribute to real projects, and grow within a collaborative development team while leveraging my project leadership and technical skills.
