Moss
Atlas
A living map of soil microbiome data for 2,400 regenerative farms.
Moss Atlas set out to turn ten years of soil microbiome research into a public atlas — usable by farmers in the field and policy teams at their desks.
Field-workers across Europe collect soil samples in areas with no cell signal. The old FileMaker workflow lost data, duplicated entries, and none of it reached the public dashboard until a quarterly manual export.
We built an offline-first PWA with conflict-free replicated state (Yjs), a MapLibre vector tile pipeline for the public atlas, and a Rails API with PostGIS for the spatial queries. Weekly field tests with actual agronomists drove the UX.
Public atlas now serves 180,000 monthly visitors. Field-workers sync 36 hours of work offline without losing a single record. The dashboard became the reference data source cited in two EU policy papers.
Same system. Every surface.
Four seasons, in order.
Three-week discovery across four field seasons. Shadowed agronomists. Mapped the data pipeline back to the lab.
Clickable PWA prototype tested with 12 field-workers in Bavaria and Andalusia. Killed two features, added one.
Shipped in 11 two-week rings. Each ring ended with a real field sync. CRDT conflict rules tuned per ring.
Launched the public atlas alongside the v2 field app. Quarterly care contract now in year three.
Moments that earn a pause.
One system, three frames.
"GreenCode treated our data like it was soil — slow, alive, worth protecting. The field team asked for no changes in the first quarter. That has never happened."
