App maintenance and rescue

How we scope the work

Start with a repeatable failure and the release that introduced it. We separate emergency recovery from larger architecture work, preserve existing user data and establish a working build before proposing a rewrite.

What the engagement can deliver

• A reproducible issue inventory and access checklist.
• A prioritised repair plan with regression coverage for affected workflows.
• A release and ownership handover, with a maintenance scope agreed separately.

What acceptance should prove

A successful repair closes the original reproduction, tests nearby workflows and records remaining risk. A maintenance agreement specifies supported versions, responsibilities and incident handling; response windows are agreed in writing.

Start with the problem you need solved

Send the current product or brief, target platforms, important integrations and a useful delivery window. We use that to propose an initial scope, identify missing evidence and agree what a completed milestone means. Commercial terms and availability are confirmed in the proposal.
