Rockstar🎓
Top SchoolDan Osborne is a senior software engineer with 11 years of experience specializing in cloud-native networking, Kubernetes security, and backend/DevOps tooling. Based in Boston, he has been a key contributor to Project Calico—working across the Calico CNI plugin, calicoctl CLI, and libcalico-go—helping harden production behaviors, improve test infrastructure, and evolve CRD and API handling for large-scale environments. At Tigera he helped integrate Calico into OpenShift and enabled self-hosted deployments, demonstrating practical expertise in real-world orchestration and systems integration. Now at CarGurus, he continues to blend backend engineering and DevOps pragmatism to deliver robust, testable systems. Beyond code, he contributes technical documentation and tooling improvements, reflecting a habit of making complex networking projects more usable and reliable. An unexpected thread through his work is a focus on testability and graceful failure modes—small changes that materially raise operational resilience.
