Resume
I am a Backend Developer focused on building robust and scalable systems using Java and Spring Boot. My background in technical 3D art has provided me with a unique perspective on system optimization, performance, and complex logic. I don't just write code; I design efficient solutions. I enjoy tackling the challenges of data persistence, API architecture, and clean code principles. My goal is to bring the same level of precision and detail I used in technical art to high-performance backend infrastructures.
