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

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.
