Rockstar🎓
Top SchoolMark Mcloughlin is a Senior Distinguished Engineer at Red Hat with 26 years of experience building and maintaining large-scale open source infrastructure, now focused on inference engineering and a vLLM committer. He has deep roots in cloud and virtualization, rising through technical and leadership roles at Red Hat and representing the company on the OpenStack Foundation board. A prolific contributor across core projects—OpenStack (Nova, Neutron, Cinder, Glance, Heat, Ceilometer), Kubernetes test-infra, OVN-Kubernetes and VLLM—he blends backend systems, DevOps automation, and kernel-level networking expertise. His recent work on vLLM improved observability (Prometheus metrics, histograms) and operational resilience for LLM serving, showing a shift from orchestration to ML inference at scale. Known for pragmatic refactors and dependency hygiene, he often focuses on maintainability and stability rather than flashy features, quietly preventing production incidents across critical projects. Based in Dublin, he also volunteers as a maths tutor, reflecting an ongoing commitment to teaching and mentoring.
