Certified Java Developer
Faculty of Organizational Sciences, Belgrade

Hi, I’m Miroslav — a backend-oriented developer with a strong foundation in Java and Spring Boot. My journey into software development began as a deliberate career change driven by the desire for meaningful, creative work. After years in an unrelated field, I invested significant time, energy, and personal savings into formal education and continuous self-education. I completed a structured Java program at the Faculty of Organizational Sciences in Belgrade, earning my Java Programming Certificate, and have since continued to deepen my skills through independent learning and hands-on projects.

Since then, I've been working on several personal backend-oriented projects, refining my understanding of software design, problem-solving, and writing clean, well-structured code. Driven by curiosity and a desire to learn continuously, I focus on building backend systems that are robust and efficient.

Although I don’t have commercial experience yet, I approach my personal projects with a professional mindset, writing tests, using CI/CD, documenting clearly, and continuously improving my skills. I'm seeking a collaborative team where I can learn from experienced developers, grow professionally as a backend engineer, and build up my ability to contribute to real-world projects.
