The same system, three times

I built the design systems at Aepsy on Base UI, and at Employment Hero and GEN on Radix. At Employment Hero that meant resolving 50+ UI inconsistencies and documenting the results in Storybook so the fixes held. At GEN the Radix system was shared across the micro frontends. At Aepsy the components serve one codebase that ships as web, iOS and Android.

Facts 01 to 05

  1. Built the design systems at Aepsy (on Base UI), Employment Hero and GEN (on Radix).

    From my CV

Employment HeroJun 2022 - Sep 2025, Radix

  1. Employment Hero: built the design system and resolved 50+ UI inconsistencies across the product, documented in Storybook.

    From my CV, Employment Hero. Counted from the team's tracking sheet during the work: entries I closed, not re-checkable now.

GENSep 2025 - Apr 2026, Radix

  1. GEN: built the Radix design system shared across the micro frontends.

    From my CV, GEN

AepsyMay 2026 - Present, Base UI

  1. Aepsy: Base UI in the stack; the codebase ships as web, iOS and Android.

    From my CV, Aepsy

  1. Storybook, Figma handoff, accessibility, internationalization.

Why it is hard

A design system is judged by other engineers' output, so the components have to hold across three codebases, platforms and teams, and the fixes only stick where they are documented.
