About

I am a highly experienced Java/Kotlin backend developer with expertise in Spring Boot, REST, microservices, and Docker. My work often involves close collaboration with customers and cross-functional teams, delivering middleware solutions and backend systems in agile Scrum environments. My background as a mathematician gives me a solid understanding of algorithms, optimization, and complex query writing.

Over the years, I’ve contributed to projects across various industries such as logistics and data management, always focusing on scalable and maintainable server-side applications. I am keen to leverage my technical and teamwork skills in a new role and excited about the opportunity to contribute immediately to innovative backend development projects.
