SVC-01: Fix an AI-built app

Your AI-built app worked in the demo. Now it breaks in front of users.

Lovable, Bolt, Cursor, Replit and v0 get you to a working screen fast. Then the bugs pile up, every AI fix breaks something else, and nobody can say why. We find the root causes, fix them properly, and leave you with code you can keep building on.

Fit check

This is for you if…

  1. 01

    Every fix creates a new bug

    You prompt the AI to fix one thing and two others break. You've stopped trusting any change.

  2. 02

    Users hit errors you can't reproduce

    Logins fail, data goes missing or pages hang, and the logs, if there are any, don't explain it.

  3. 03

    Nobody knows what's in the code

    The app was generated faster than anyone could read it. You need someone who will.

  4. 04

    You have users or a launch date

    Starting over isn't an option. You need it stable this month, not a rewrite next quarter.

Deliverables

What you get.

  1. D-01

    Root-cause diagnosis

    A written breakdown of what's failing and why, ranked by user impact, in plain language.

  2. D-02

    Fixes that hold

    Targeted changes to code, data model and config, each reviewed by a senior engineer before it ships.

  3. D-03

    Tests around the fragile parts

    Automated tests on the flows that broke, so the same bug can't quietly come back.

  4. D-04

    Error tracking and logs

    Monitoring that tells you about problems before your users email you.

  5. D-05

    A clean handoff

    Notes on what changed and how to keep prompting the codebase without undoing the fixes.

Salvage report

What we keep vs. what we replace.

We don't rewrite what works. Most AI-built apps have a sound core wrapped in a few bad decisions.

Keep

  • Screens and flows your users already know
  • Your hosting and database provider, when they fit the job
  • Working business logic and existing data
  • Your ability to keep building with AI tools

Replace

  • Auth and permission logic that leaks or fails open
  • Duplicated, conflicting code left over from earlier AI attempts
  • Secrets and API keys exposed in the browser
  • Queries and schema choices that fall over under load

Flight plan

How this mission runs.

  1. 01
    Day 1

    Intake

    You share repo, hosting and database access. We confirm what's broken from your users' side.

  2. 02
    Days 2–5

    Diagnose

    We trace the failures, read the code that matters and send a ranked fix list with effort estimates.

  3. 03
    Weeks 2–3

    Fix and test

    Fixes ship in small, reviewed batches with tests, starting with whatever hurts users most.

  4. 04
    Week 4

    Stabilize and hand off

    Monitoring goes live, we walk you through the changes and agree on what's next.

// Typical timings. We confirm yours in the written mission plan.

FAQ

Questions we hear.

Something else on your mind? Ask it on the call. That's what it's for.

Book a call
Do you work with apps built in Lovable, Bolt, Replit, Cursor or v0?

Yes. That's most of what we see. We work in your existing repo and keep it compatible with the tool you used, unless the tool itself is the problem.

Will you just rewrite everything?

No. A rewrite is rarely the fastest path. We fix what's broken, keep what works, and only recommend rebuilding a part when patching it would cost more.

Can I keep using AI tools after you're done?

Yes. We leave structure and notes that make AI edits safer, and flag the areas where changes should get a human review.

What do you need from me to start?

Access to the code repository, hosting and database, plus a list of what's broken from your users' point of view. Screenshots and error messages help.

What if the problem is bigger than expected?

You'll know after the diagnosis, before any larger commitment. We tell you plainly what it'll take and you decide.
