JavaPHPArchitekturAutomatisierungContinuous IntegrationSkalierbarkeitPythonWorkflowsSpring BootBackendFront End
I’m a Software Engineer with 6+ years of hands-on experience in backend development, automation, and delivering scalable systems in cross-functional teams. My core focus is on Java, Spring Boot, and modern CI/CD workflows, with a growing interest in Python and continued flexibility for fullstack collaboration.
I’ve contributed to projects across industries and team sizes - including greenfield builds where I took ownership of backend development, contributed to architecture, and set up CI/CD pipelines from the ground up. I also bring experience working with frontend frameworks and enjoy collaborating across the stack.
