Fieldkit Ops

Fieldkit: Mobile ops app for on-site crews

A cross-platform mobile app for field crews to capture job updates, photos, and checklists that sync back to the office.

Operations

Person using a smartphone outdoors for mobile work

Challenge

Problem space

Field crews needed reliable job updates without depending on perfect connectivity.

Business impact

Late status, missing photos, and duplicate data entry when back in the office.

Solution direction

Offline-capable mobile clients, conflict-safe sync, and a stable API for the existing ops console.

Solution

We built iOS and Android apps with offline-friendly job forms, photo capture, and sync to a central API the ops team already uses.

What we shipped

  • iOS and Android apps
  • Offline job forms
  • Photo capture
  • Sync queue
  • Shared ops API

Architecture

Local-first forms with sync as a background job. Server remains the source of truth once acknowledged.

iOS / Android apps
  -> Local queue
  -> Sync API
  -> Jobs store
  -> Ops web console

Mobile clients

Job lists, checklists, photo capture, offline queue.

API

Auth, job CRUD, media upload, sync acknowledgements.

Ops

Existing console reads the same job records.

Engineering challenges

Offline reliability

Friction

Crews lose signal on sites.

Solution

Queued mutations with retry and clear UI for pending vs synced state.

Photo ownership

Friction

Images arrived without job context.

Solution

Upload tied to job id with placeholder thumbnails until sync completes.

Impact
Office sees progress without chasing crews
