We deal with distributed systems, we started with client-side load balancing with Feign/Ribbon because we were using eureka as service discovery, and then we moved to use Kubernetes services. - Agile methodologies and software practices: Scrum, CI/CD, Domain-Driven Design, TDD, Hexagonal architecture. Stack: Kotlin, PHP, Java, Spring, Spring Cloud, Ribbon/Feign, Eureka, Zuul, AWS, Kafka, Cloudformation, Kubernetes, Spinnaker, Archaius, Avro, ElasticSearch, Redis, Github, Jenkins, TravisCI, JUnit, Mockito, Mockk, AssertK, AssertJ, Gradle, Docker, Datadog, Logstash, Kibana, PostgreSQL, MariaDB, KrakenD. Adevinta is a marketplace specialist.
