Experience
Workyard
Design Systems Lead
Sep 2025 – Current
Sydney, AU
Designed Workyard's cross-platform product features end-to-end, building wireframes, user flows, and high-fidelity interactive prototypes in Figma that handed off cleanly to engineering.
Worked closely with the Head of Product and product managers, bringing design, engineering, and sales onto the same page, setting priorities early and turning business needs into shipped features.
Shipped, watched how people actually used the product, and refined from there, backed by a design system that held up as the team grew.
Built AI design systems with Figma MCP and design guidelines, enabling PMs and engineers to design solutions across each product line and move faster with feature releases.
