Model 04 · Application Maintenance
Your software in safe hands.
The last developer who understood your application has left the company? Your Sencha ExtJS application runs, but no one dares to change anything anymore? A framework update has been overdue for years because the risk seems too great? That is exactly what application maintenance is for.
The starting point
The health check.
We analyze your existing application — framework version, security gaps, technical debt — and deliver a written short report with concrete options for action and a rough effort estimate. At a fixed price, so the decision to "take a look" doesn't need major sign-off.
Note: the health check is specifically for Sencha ExtJS applications. For a stack-independent assessment, see Code Audit. Depending on the result, the next step is a manageable modernization in stages, permanently more capacity through team augmentation, or — if the application can no longer be saved — new development.
