An industrial client records workplace incidents, and the records only matter if a safety lead can see a pattern in them. The interface answers one question at a glance — which zones are hurting people — by mapping incidents to physical locations as heat and clusters, so the intensity is read before any number is.

A data-dense map view is easy to make loud and hard to make readable. The heat scale carries the signal with a single hue, clusters get an explicit boundary rather than another colour, and the surrounding UI stays quiet so nothing competes with the map. It holds up responsively — the same view works on a laptop in an office and a tablet on the floor.

The visual design arrived as a Figma design system, and my job was fidelity: buttons with every specified state, modals, reactive forms including a map position picker for placing an incident precisely. Tokens and interaction specs implemented as given, not reinterpreted — when a design system is delivered that carefully, the useful contribution is discipline, not opinion.

CSV export. The map answers where, but the reporting lives in spreadsheets and regulator paperwork, so getting the data back out was a first-class requirement rather than an afterthought bolted to a menu.
