Carlos Aguirre Orozco
Designer & EngineerAgent Orchestrator
When I'm not running from dinosaurs or terraforming a new planet, I'm cooking. Most of the time it's interfaces: I design them, then build them.
I led design and frontend at Sourcetable, an AI spreadsheet, working directly with the CEO: the brand, the AI chat, the whole product surface. Before that, three years building at Thomson Reuters. Now I build the guardrails for AI-built UI: the checks that catch what the agents get wrong.
