Hi, I'm Anđela Ljubenković

Java Software Engineer | Backend Development | Distributed Systems

I’m a software engineer with over three years of experience developing backend applications and real-time payment systems. I hold a Bachelor’s degree in Software Engineering and primarily work with Java, Spring Boot, microservices, SQL, and relational databases.

My professional experience covers the full software development lifecycle, including requirements analysis, implementation, automated testing, documentation, CI/CD, Kubernetes deployment, application monitoring, and production support.

I enjoy understanding the business processes behind the software I build and turning complex requirements into reliable, maintainable solutions. Alongside backend development, I have also worked on full-stack and mobile applications.
