# TJ Pitre

Named Context-Based Design Systems: systems that carry what a component means, how it behaves and when it applies, not only what it looks like. Splits the work into authoring, which is judgment-heavy, and enforcement, which must be boring.

Listed as Founder and CEO of Southleft on the Into Design Systems 2026 speaker page; a LinkedIn headline reading Product Architect, Design Systems at Figma also appears in search results and is unconfirmed here.
