Ivan Leo builds and evaluates autonomous agents for a living — he shipped production agent tooling at Manus before moving to Google DeepMind's Gemini developer-experience team — and his recent public output is a series of live, from-scratch builds of research agents and coding-agent harnesses, backed by his own benchmark numbers on what actually works.
