Session (1)
Kenton Varda is the principal architect of Cloudflare Workers and the creator of Cap'n Proto, and his recent work on Dynamic Workers (AI agent sandboxing with V8 isolates, ~100x faster than containers) and "Code Mode" MCP approaches makes him a strong draw for anyone building AI agent infrastructure. His talks and writing show he is actively shaping how AI-generated code can be safely executed at scale, from practical sandboxing architectures to rethinking how LLMs should interact with APIs.
