About Me
I'm a Senior Software Engineer with over 13 years of experience designing and delivering high-availability distributed systems for the Healthcare and Automotive industries.
Currently at Caresyntax GmbH in Berlin, I architect mission-critical microservices using Java 21, Spring Boot 3, and AWS/Kubernetes — systems that literally support surgical operations worldwide.
I'm passionate about Domain-Driven Design (DDD), event-driven architectures, and leveraging AI-augmented development workflows (Claude Code, GitHub Copilot) to accelerate team velocity without compromising quality.
Outside engineering, I'm actively learning German (A2)and enjoy exploring Berlin's vibrant tech community.
