Summary
🤩
Rockstar🎓
Top SchoolGreg Rutz is a senior principal engineer and technical leader with 11+ years of experience building large-scale video and AI systems, currently shaping Comcast’s Developer Experience platform for internal and customer-facing AI solutions. He blends deep expertise in language-focused AI (LLMs, LangChain, LangGraph, semantic routing, fine-tuning Llama3) with a long history in streaming media, DRM, and embedded/IP video architectures. At Comcast he’s led innovation efforts that produced production-ready products, built Kubernetes GPU clusters from bare metal, and created agent-enabled personal assistant platforms that integrate voice, speaker recognition, graph databases, and tool-driven workflows. A hands-on engineer who mentors teams, he couples practical infrastructure skills (Python, Rust, Kubernetes, Ansible, Helm) with researcher instincts—often fine-tuning models and designing semantic routers to solve real-world problems. Based in Arvada, Colorado, he’s equally comfortable prototyping low-level media stacks and evangelizing AI-assisted development workflows to large engineering organizations.
