About

As a Back End Engineer, I have successfully taken multiple projects from 0 to 1. I am a strong independent contributor, that really enjoys to be part of a collaborative team. Currently, I work mostly with Java, Kafka and deploy software using k8s. I have over 7 years of experience in working with companies in the Netherlands.
