Nikola Djordjevic

I’m a backend software engineer with 5 years of professional experience building Java-based enterprise applications. I focus on production-ready backend systems—designing microservices, shipping RESTful services, and ensuring reliability through strong testing and disciplined engineering practices.

On every project, I take ownership of multiple backend microservices and support them in real environments. With on-call experience, I reproduce and resolve issues and bugs across production, staging, and develop environments, and I’m comfortable collaborating in Agile/Scrum teams on international projects.

My day-to-day work blends both design and implementation: I build backend server-side logic using Spring Boot, Maven, and Hibernate, integrate with relational databases like PostgreSQL/MySQL and Oracle/Microsoft SQL, and also work with NoSQL using ArangoDB. I communicate between services using GRPC and Kafka, and I follow TDD—maintaining at least 80% coverage through integration and unit tests.

I’ve delivered across different domains, from portfolio analytics (microservices backend with REST, GRPC, Kafka, Liquibase, and AWS) to insurance platforms where I developed backend services, wrote scheduled Java batches, implemented client-requested improvements, and handled frequent SQL and PL/SQL work. I’m a self-starter who’s comfortable multitasking, and I strive to exceed expectations while delivering measurable outcomes.
