In this keynote, Luis Hector Chavez, Chief Technology Officer at Replit, takes the idea of autonomy past the coding agent and applies it to the company itself. Learn what changes when the systems that build, test and ship software can increasingly run their own loops - and what that means for the people and processes wrapped around them.
Luis, who leads engineering at Replit and previously worked on bringing Android applications to Chrome OS, brings the perspective of someone building the environment where a large share of AI-assisted software now gets written.
