Ledger design system — Northbeam Systems
2024 — 2026
Lead designer · 4 engineers · 9 product squads
Northbeam had three divergent component sets and no shared token layer. I led the consolidation into one system covering web, the internal operations console and the embeddable reporting widget.
- Audited 240 interface patterns down to 54 components, documenting what each one replaced so squads could migrate without guessing.
- Designed the token architecture — colour, type, spacing, elevation and motion — with semantic aliases that let a theme change ship without touching component code.
- Wrote the contribution model: a request template, a weekly triage slot and a written definition of done covering keyboard paths, focus order and reduced-motion behaviour.
- Rebuilt the data table as a composable primitive with sticky headers, column resizing, inline edit states and a documented empty/error matrix.
