X Career
In a first-person interview, Gil Guzman describes engineering study at Télécom SudParis and specializing in video-game development. She joined Microsoft for a final internship and continued as a software engineer, working across customer and product teams. She later cofounded Emera as CTO through OSS Ventures, moving from contributions to many projects toward responsibility for a whole product. Her current public professional account identifies OpenAI.[2][5]
Contributions
Keep multiple views tied to the same editable scene
Her Architecture Studio showcase builds a room planner around one document shared by a dimensioned floor plan and a synchronized 3D view. Furniture placement, rotation, finishes and undo all operate on the same room state. The published build process also addresses export, device layout and saving. This demonstrates how an agent-built visual prototype can become an inspectable editing workflow instead of a static rendering.[4]
Expose material choices through immediate visual feedback
Material Lab is a browser tool for changing surface properties and lighting on a sculptural object. Its controls include roughness, metallic appearance, translucency, color and light intensity, with immediate updates, before/after comparison and saved presets. The showcase’s build brief ties those parameters to an interaction a user can see and adjust without editing shader code.[3]
