I'm a product designer who turns complexity into clarity for B2B products. I explore ideas through prototypes and shape experiences that feel natural and intuitive.
Recently, I built a prototyping playground where designers at ToolTime can prototype directly in code. I also designed a new ToolTime Pay feature that lets craftsmen pay their outstanding invoices themselves.
Time tracking for craftsmenMobile-first time tracking for craftsmen juggling ladders, calls, and unpredictable schedules.
ToolTime PayBank transfers, reconciliation, and dunning for German tradespeople. Designed around the edge cases when automation fails.
Scaling ToolTime's design systemSemantic token architecture, Figma-to-code workflow, and team adoption strategy for a multi-brand design system.
