Summary
🤩
Rockstar🎓
Top SchoolEllis Tarn is a Principal Software Engineer with 11 years of experience building cloud-native and ML infrastructure, currently focused on making Kubernetes easier at AWS EKS. He combines deep open-source pedigree—creator of Karpenter and early contributor to KServe/KFServing—with a strong product sensibility, preferring early-stage work that reduces long-term technical debt. His background spans leading inference and finetuning services at Meta and Vertex AI Inference at Google, giving him rare cross-cutting expertise in compute, networking, storage, and model serving. Pragmatic and hands-on, Ellis architects foundational systems (autoscaling, admission webhooks, deployment mutators) while keeping product-market fit front of mind. Based in Seattle, he often gravitates toward projects where rethinking assumptions yields disproportionate impact.
