Backendz Field
Apps that keep working where the signal does not.
A dedicated mobile app team for iOS and Android
Mobile engineers who build for the people using the app in a warehouse, a van or a basement plant room. Offline-first by default, with sync that does not lose a job.
- Vetted in four stages
- In place within days
- Your codebase, your tools, your standups
- Code and IP transferred to you
- One UK company accountable
Lose the signal. Keep the work.
Turn the phone's signal off, complete a job, then bring it back and watch it sync.
Offline-first
No signal: the app keeps working
Every action is saved on the phone first and sent when there is a connection. The engineer finishes the job, signs it off and moves on; the office sees it the moment the van finds a signal.
Tap a job to complete it. Then switch the signal on.
Build the squad
The core roles are switched on. Add the others the work needs; we will propose the people for each.
Your Mobile team
3 roles, one accountable lead
Mobile engineer, Back-end engineer, Product designer. Full-time or part-time each, for a sprint or the long term, in your codebase and your standups.

From first call to first sprint
Your team in place within days. Working software at the end of the first sprint.
- Scope callThirty minutes on what you are building, what is in place and what the team needs to own.
- Line-upWe propose the roles and the people, with their experience, and you meet them before anything is signed.
- OnboardingAccess, environments and the first tickets agreed. The team joins your tools and your standups within days.
- First sprintWorking software at the end of it, reviewed with you. The team grows or shrinks with the work from there.
How we vet engineers
Four stages, before anyone joins your work. You meet the people we propose before anything is signed.
- Portfolio & experience reviewRelevant projects, technical depth and hands-on experience are reviewed first.
- Technical assessmentA practical task tests code quality, problem-solving and the stack the project uses.
- Quality & team reviewSenior engineers review the work for implementation quality, communication and collaboration.
- Final approvalConfirmed against the project's requirements and Backendz's quality standards before joining a team.
Engage the way the work needs
- Dedicated teamA full squad owns an outcome: a product, a platform or a programme of work, with a lead who answers for delivery.
- Team extensionEngineers join the team you already have, in your codebase, your tools and your standups.
- Full-time or part-timeEach person is assigned for the hours the work needs, not a fixed block.
- A sprint or the long termStart with one sprint to prove the fit, then keep the team for as long as the roadmap runs.
Questions we are asked
Do you build native or cross-platform apps?
Mostly cross-platform with React Native, so one team ships iOS and Android from one codebase. A native engineer joins when a feature needs the platform directly.
What does offline-first mean in practice?
The app saves every action on the phone first and syncs when there is a connection, so a job completed in a basement is never lost and nobody waits for a spinner.
Can the team build the back end as well?
Yes. A back-end engineer is part of the core line-up and builds the API and the sync service the app depends on.
Do you publish to the App Store and Google Play?
Yes. The team sets up the store listings, the build pipeline and the release process, under your developer accounts.
Who owns the app?
You do. The code, the store accounts and the intellectual property are yours, transferred under the contract with no licence fees.
