Halden sells basemaps and routing to logistics companies. I own the map interface layer: the style editor customers use, the component library our four product teams share, and the render pipeline that turns both into something a browser can hold at sixty frames.

• Rebuilt the style editor on MapLibre and PMTiles, cutting the tile bill by about a third by serving one range-requested archive instead of forty million small objects.
• Wrote the token pipeline that publishes one Figma file to CSS, Swift and Kotlin. Colour and spacing stopped being a code review argument.
• Took the shared component library from a folder nobody trusted to a versioned package with a written deprecation policy and visual regression on every PR.
• Introduced a contrast audit that measures type against the map tiles actually rendered underneath it, which is the only measurement that means anything over a basemap.

Interactive desk at a daily paper. Election nights, budget explainers, one flood map that had to be right before it was pretty.

• Built the graphics toolkit the newsroom still uses: chart primitives, a scrollytelling scaffold, and a build that publishes a story as a self-contained embed.
• Cut the standard embed from 340KB to 60KB, which on election night is the difference between a page that loads and a page that does not.

Monitoring dashboards for offshore wind. Thirty operators watching four hundred turbines, mostly at night.

• Replaced a polling grid with a streamed one, so an alarm reached the operator in under a second instead of up to thirty.
• Rewrote the alarm colours after a night shift walkthrough: the old palette failed on the room's own screens and on two of the operators.

A six-person agency. Museums, festivals, one municipality, and whatever else came through the door.

• Shipped eleven sites in fifteen months and learned, the hard way, what a component is for.
