Aleksandar Kitanovski
@aleksandarkitanovski
Java Backend Developer specializing in Spring Boot, REST APIs, and test-driven backend systems.
What I'm looking for
I am a Java backend developer focused on building production-grade services using Spring Boot, REST APIs, and robust testing practices such as JUnit 5 and Mockito. I emphasize secure authentication (JWT access/refresh with rotation and server-side revocation), clear code, and maintainable architectures.
As a career switcher with 6+ years in high-responsibility roles, I bring strong ownership, process discipline, and effective communication from prior offshore and inspection leadership experience. I have delivered backend APIs, indexed large document corpora into Elasticsearch, and shipped client desktop applications using Windows UI Automation and Docker-based development flows.
I look to grow within collaborative teams that pursue high code quality through reviews and testing, contribute to production-grade backend services, and continuously improve via learning and practical project work.
