Marcos Rezende

I design AI systems that people can supervise, reverse and audit.

Senior product designer at Hive, with 16 years in product design and the last several focused on AI: agentic workflows, automation and design systems shipped as code. Before Hive, I led design for SharePoint News and AI experiences in the Microsoft 365 Copilot ecosystem at Microsoft, and designed AI, ML and automation features at Qlik.
