Beschreibung

Senior Java Backend Developer with 12+ years of experience building scalable, reliable systems using Java 8+ and the Spring ecosystem (Spring Boot, Security, Data). Specialized in designing and delivering robust REST APIs, domain-driven architectures, and high-performance backend services in regulated and data-rich environments (healthcare, mobility/automotive, hospitality).
