Back to original languageAbout Kevin
As a Senior Software Engineer with over 20 years of experience, I specialize in backend development with Kotlin/Spring Boot, Python, and cloud technologies from Azure and AWS. My focus is on implementing scalable, high-performance backend solutions, as well as modeling and managing relational and NoSQL databases. I have in-depth knowledge of microservices architectures, API development, data integration (ETL), and data engineering in the enterprise environment.
Additionally, I bring experience in developing mixed-reality products (Augmented Reality and Virtual Reality), particularly with Unity and C#. My work approach is characterized by agile methodologies (Scrum, TDD, Clean Code). I combine technical excellence with a deep understanding of complex system architectures and modern software engineering standards. My projects include energy optimization solutions, digital twins, and enterprise applications in the financial and energy sectors. I am available for global assignments, but prefer assignments in the Rhine-Main region or remote.
