I’m Sam Partee, CTO and co-founder of Arcade.dev. I started Arcade in 2024 with Alex Salazar to build the runtime layer for agents - the secure action layer that lets AI agents take real, authorized actions on behalf of real users.

Before Arcade, I was Principal Applied AI Engineer at Redis, where I led the applied AI team and built out the company’s vector search and LLM tooling - including RedisVL. Earlier, I worked on ML infrastructure for high-performance computing at Hewlett Packard Enterprise and Cray, where I created the SmartSim AI framework and published research on applying deep learning to climate models.

I’m an avid open-source contributor (LangChain, DeterminedAI, and Chapel, among others) and I hold a CS degree from Haverford College.

This site is where I write about whatever I’m currently obsessed with - lately that’s AI agents, MCP, tool calling, and agent authorization. Browse the notes, or dig into the posts.
