Overview
The technician app for jobs, time, photos, schedule, and nested checklists, shipped as 1.1.x–1.2.x with Expo EAS profiles, WatermelonDB offline storage, and TanStack Query sync on unreliable networks.
A technician’s day is vans, ladders, and clients who are already waiting. This app is the shortest path from “I finished the work” to “the office can see it”: clock time, attach photos, update status, run nested checklists, and get a push when something changes.
Releases 1.1.x through 1.2.x went out through Expo EAS profiles. Offline is not a slogan: WatermelonDB holds the local record, and TanStack Query syncs when the network returns, so checklists and job updates do not depend on a perfect connection.
What it covers
- Field-first flows: jobs, time on site, photos, schedule, alerts, and nested checklists.
- Offline storage and sync aimed at unreliable networks, not demo-mode airplane-mode theater.
- EAS release profiles so staging and production builds stay distinct.
How I contributed
- Shipped 1.1.x–1.2.x through Expo EAS release profiles.
- Implemented WatermelonDB offline storage and TanStack Query sync.
- Built nested checklist execution that still works when the signal drops.
Outcomes
- Shipped FieldGrid mobile 1.1.x–1.2.x with Expo EAS release profiles.
- Added WatermelonDB offline storage for technicians who lose signal between stops.
- Synced field data through TanStack Query so the office sees the same job truth as the truck.
- Built nested field checklists that stay executable when the network flickers.
