Alex Fournier

AI Engineer · NVIDIA Engineering

I build open-source infrastructure for AI agents, with a focus on observability, secure execution, model routing, evaluation, identity, and GPU-accelerated retrieval.

My recent work includes building and upstreaming the core NeMo Relay integration for Hermes Agent, along with broader contributions to Relay's plugin, safety, and observability systems. During summer 2026, I was one of Hermes Agent's most active contributors.

I also contribute across NeMo Switchyard, OpenShell, NemoClaw, NeMo Agent Toolkit, NeMo Gym, and cuVS.
