Name:Guilherme Herzog

Bio:

I am a Sr. Software Engineer at Google working on AI features for Developer tools including Cider, our internal IDE.

Originally from Rio de Janeiro, my work focuses on the intersection of UX and AI. Within the Cider AI team, I help build tools driving Google’s milestone of 25% AI-written code. I was a lead engineer for Smart Paste, an LLM-powered feature that adapts pasted code, modifying millions of characters weekly and accounting for 1.2% of all code written company-wide

Currently, I work on the team behind Google’s most used internal coding agent: Cider Agent & Gemini Coder. We are transforming Google’s software development lifecycle with agentic tooling.

Outside work, I enjoy 3D printing, triathlon, and playing tennis.
