Playground

This is where I make things I want to use myself.

Some start inside my design work. VariantHub lets me generate interface directions in the repository and compare them in the real layout before choosing one. UX Planner keeps personas, journeys, and user flows close to implementation, where I can review and edit them instead of losing them in static documents.

Other projects start with interests outside work. Margy grew from years of making pizza and switching between paper notes, spreadsheets, calculators, and memory. Building it lets me test product decisions against a process I know first-hand.

I use these projects to stay hands-on. Early versions expose details that static screens hide, and working through those details in code shows me whether an idea is useful or needs another pass.

What lives here
