What I'm looking for

I am looking for roles that emphasize backend excellence, clean architecture, and opportunities for engineering scalability.

I am a Backend Java Developer with 17 years of experience in delivering scalable and high-performance systems across various sectors including finance, energy, and e-commerce. My expertise lies in Java (versions 8, 11, and 17), Spring Boot, and Microservices architecture. I have a strong command of modern engineering practices such as TDD, SOLID principles, and hexagonal design, which I apply to create robust and efficient backend solutions.

Throughout my career, I have successfully collaborated with cross-functional teams in Agile environments, delivering global solutions for prestigious clients like Google and major banks. My hands-on experience with AWS, Docker, and Kubernetes has enabled me to implement cloud-native deployments and CI/CD pipelines effectively. I am passionate about backend excellence and engineering scalability, and I am currently seeking remote or relocation roles that align with these values.
