Java Backend Developer at Engineering Albania building Spring Boot services and Kafka event-driven microservices.
What I'm looking for
At Engineering Albania, I develop and maintain production Spring Boot services on an enterprise platform running in OpenShift. I implement event-driven communication between microservices with Apache Kafka and maintain Jenkins CI/CD pipelines through deployed releases.
At Full Screen Digital, I designed, built, and extended Spring Boot REST APIs for a fully remote client. I worked across Oracle DB and PostgreSQL on schema changes, query tuning, JPA mappings, and data migrations.
I also built Slottify, a multi-tenant appointment scheduling API secured with Keycloak. It includes tenant isolation, booking-conflict detection, PostgreSQL migrations, and JUnit 5 and Mockito tests.
