App rescue and takeover

Your app fails in production and the people who built it are gone, or it was built with AI tools and nobody fully understands it. We take it over, stop the incidents, then fix the causes.

When an app needs a rescue and takeover

  1. 1.

    Orders stop syncing and nobody can say why

  2. 2.

    The previous developer or agency stopped answering

  3. 3.

    An AI-coded app worked in the demo and fails under real orders

  4. 4.

    Every fix creates two new incidents

A failing app and a missing previous vendor are taken over; triage, containment and fixes restore the order flow, add monitoring and leave runbooks owned by the client.accesscode / credentialsfixeddocumentedFAILING APPincidents / no ownerPREVIOUS VENDORno handoverTAKEOVERtriage / contain / fixMONITORINGalerts / logsORDER FLOWrestoredRUNBOOKSowned by you

What the engagement covers.

  1. 01

    Triage

    What is failing, how often, and what each incident costs.

  2. 02

    Containment

    Retries, alerts and manual fallbacks so sales continue while we fix.

  3. 03

    Root causes

    Each incident traced to code, data or infrastructure and fixed there.

  4. 04

    Ownership

    Repositories, cloud accounts and credentials moved under your control.

  5. 05

    Documentation

    Runbooks and technical documentation, so the system has an owner again.

How it runs.

  1. P01

    Triage

    Find what fails, how often and what it costs.

  2. P02

    Contain

    Stop the bleeding so orders keep moving.

  3. P03

    Map

    Read the code end to end; write down hidden business rules.

  4. P04

    Fix

    Replace weak parts one at a time, verified against the old path.

  5. P05

    Hand over

    Ongoing support, or a clean handover to your team.

What you get.

Questions engineers ask us.

Q01Can you take over code you did not write?

Yes, that is the job. We read it end to end before changing it and keep the business logic that works.

Q02What about apps built with AI tools?

Same approach. AI-written code often runs until real volume arrives; we find the weak parts and fix or replace them one at a time.

Q03Do we have to stop selling while you fix it?

No. Containment comes first so orders keep moving; fixes then go in component by component.

Q04Who owns the code and accounts afterwards?

You do: source code, repositories, cloud accounts and credentials.

Describe the app, what fails and since when. We start with triage, not a sales deck.
