Rockstar🎓
Top SchoolMichał Dulko is a Senior System Software Engineer with 20 years of experience specializing in OpenStack, Kubernetes and OpenShift integrations, now working at NVIDIA after a multi-year tenure at Red Hat. He is a seasoned backend and DevOps engineer who has contributed to high-profile open-source projects—maintaining OpenStack and Kubernetes components and improving OpenShift installer, cluster-network-operator, and Kuryr integrations. His work often targets cloud-native networking and load-balancer stability on OpenStack, including fixes for LoadBalancer FIP deletion, Octavia integration improvements, and parallelized resource teardown to speed cluster destruction. Comfortable moving between code and infrastructure, he combines Cinder core review experience with pragmatic operational changes that reduce failure modes in production clusters. Based in Gdańsk, Poland, he pairs a formal MSc in Computer Science with a track record of impactful upstream contributions that many operators rely on behind the scenes. An uncommon strength is his focus on OpenStack-specific edge cases within Kubernetes/OpenShift stacks, making him particularly effective at bridging cloud provider gaps.
