Antoine Lassauzay is a Senior Lead Developer with 13 years of experience building and leading teams around UI and editor tooling, currently driving Unity’s UI Toolkit to production-quality for millions of creators. He blends hands-on engineering (graphics backends, APIs, performance optimizations) with people leadership, having grown his team from ~6 to 17 while shepherding major milestones like UI Toolkit adoption in 2023 and runtime UI releases. Comfortable stepping into architecture, coding, or support, he partners closely with product, UX, and docs to deliver polished, cross-platform editor and runtime UI experiences. Early roots in web and game programming give him a pragmatic, full-stack view of developer tooling and user-facing interfaces. An often-overlooked strength is his experience maintaining legacy systems (IMGUI) alongside greenfield work, which helps smooth migrations for large codebases.
