to your stack & domain
Build a mobile app that remains useful without connectivity and safely syncs state when the network returns. Ends field-tested against real network conditions.
How this operator works
every way of working, already decidedOwns the system, not the ticket
Takes end-to-end ownership of a service or surface. Design, delivery, on-call. And is measured on outcomes, not hours.
Embedded, async-first, instrumented
Works inside your repos, your CI and your rituals. Daily written standups, decisions logged. No status-meeting tax.
Runbooks, canaries, reversible deploys
Every change gated and reversible. Incidents get a timeline and a postmortem; nothing ships without a rollback.
Plugged into your Slack & rituals
Joins standups and retros, reports weekly against the goal. You get an operator, not a queue.
Brings a pre-wired stack or adopts yours
Infrastructure and observability as code by default. No bespoke setup tax to absorb.
Scoped, gated, reversible
Week-1 shadow, week-2 ownership, swap on request inside the trial window. No long-tail handover risk.
Overview
Field teams, drivers, inspectors, and anyone working in basements or rural coverage share one truth: the network is a sometimes-thing. An app that shows a spinner when offline is an app they stop trusting. The Offline-First Mobile App Build inverts the architecture — the device's local store is the source the app works from, and the network is an optimisation, not a dependency.
The finish state is an app that stays useful with no bars: users read, create, and edit offline; changes queue and sync safely when connectivity returns; and conflicts resolve by rules the business chose, not by silent data loss.
What's included
Local-First Data
An on-device store holding the data each user needs, scoped and encrypted, with the app reading and writing locally for instant response.
Sync Engine
Background synchronisation that handles partial transfers, retries, ordering, and battery courtesy — engineered against flaky networks, not just absent ones.
Conflict Resolution
Per-data-type rules for concurrent changes — merge, last-writer-wins with history, or human review — agreed with you in scoping and tested deliberately.
Degraded-Mode UX
The interface tells the truth: what is synced, what is pending, what failed and why — so users trust the app precisely because it is honest offline.
How it works
- Scope — Fix the offline scope per workflow, the data each role carries, and the conflict rules per data type.
- Build — Build the local store and sync engine first, then the workflows on top, tested under simulated network chaos.
- Handover — Store launch, field-condition test results, and full source handover including the sync runbook.
Part of every Delivery Plan
The Offline-First Mobile App Build is a menu item on the Scrums.com delivery catalog, available at every plan tier. Add it to your plan backlog and your delivery team schedules it like any other item — scoped, tracked, and reported through the SEOP. See Delivery Plan Tiers.
FAQs
Can you retrofit offline capability into our existing app?
Sometimes — it depends on how the current data layer is built. The scoping audit gives an honest verdict: retrofit, partial rebuild of the data layer, or new build. Offline-first is an architecture, not a feature flag.
How do you prevent data loss in conflicts?
No change is discarded silently: every conflict resolution retains the losing version in history, and rules are explicit per data type. The awkward cases are enumerated in scoping and turned into tests.
How much data can the device hold offline?
Scoping sizes it per role — a field worker's day, a week's route, a site's records. The sync engine manages the local footprint so old data ages out by policy rather than filling the phone.
