Hi, I'm Uros Ilic 👋

🚀 About Me

I'm a backend engineer specializing in scalable, maintainable, and secure systems using Java, Kotlin, and Spring Boot.
I design and implement robust solutions for a wide range of industries — from business platforms and B2B APIs to analytics and automation.

My approach:

  • Robust, modular codebases
  • Domain-driven design and industry best practices

I value direct written communication and always deliver clean, production-ready solutions tailored to client needs.
