What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my extensive experience in backend development and cloud solutions to drive impactful projects.

With over 25 years of experience in IT, I have honed my skills as a backend software engineer and Java technical leader. My expertise spans planning, development, debugging, and refactoring systems across various languages and platforms. I believe that a comprehensive perspective combined with deep knowledge is essential for creating stable and maintainable architectures.

I am a dedicated team player with excellent interpersonal skills, committed to continuous learning and sharing insights with colleagues. My recent projects include advanced LLM integration with Spring and langchain4j, where I designed a modular architecture that integrates cutting-edge AI technologies. I take pride in my ability to lead complex projects, such as the development of a cloud-based oncology treatment recommendation system at Philips Medical, where I successfully coordinated multiple microservices and enhanced team onboarding processes.
