Using publicly available information we constructed an analysis to help you get a feel for this speaker before deciding to attend their session.
Varda is the creator of Cloudflare Workers, Cap'n Proto, and the new Cap'n Web RPC system, so his session is a chance to hear the architect of the edge-compute and JavaScript-RPC stack explain — with live code — how capability-based RPC and isolate sandboxing reshape how we build APIs and safely run AI-generated code.
