AI-Broken Store Rescue

Your AI-built store broke in production. I fix what the AI got wrong — for a flat price.

AI and 'vibe-coding' ship stores that look done and fail where it counts: 500 errors, broken checkout, payments that don't complete, security holes. I find what's actually wrong, fix it, and prove it live — flat price, no hourly meter. Senior engineer, 125k+ lines of production code.

  • 2,000+ orders/mo on my own store
  • 150K visits/mo · 9+ ROAS
  • 6+ yrs production
  • 125k+ LOC WooCommerce/PHP

AI wrote code that passed a demo and broke on real customers

AI coding tools are great at confident-looking code and terrible at the parts that only fail in production — concurrency, payments, security, edge cases. So you got a store that demoed fine, shipped, and now loses orders or throws errors with real traffic.

  • 500 errors or white screens under real load
  • Checkout that fails, double-charges, or never completes the order
  • Payments that succeed at the processor but don't mark the order paid
  • Security holes — exposed keys, injection, no input validation
  • Data that saves wrong, or not at all
  • Code no one can safely change because nobody understands it

This is now a common, expensive failure mode

Studies through 2025–26 found a large share of AI-generated code needs manual rework and ships exploitable vulnerabilities, and a meaningful chunk fails in production after passing QA. You're not careless — this is what the tools do. The fix is a human senior engineer.

  • A large share of AI-generated code needs manual fixes before it's production-safe
  • A significant portion ships with security vulnerabilities
  • 'Passed QA' and 'survives real traffic' are not the same thing

How it works: triage first, then a flat-price fix

  1. 1 Book the 48-hour triage. I reproduce the failure and scope the real damage.
  2. 2 You get a written plan plus a single flat fix quote (typically $2,500–$6,500).
  3. 3 The $690 triage is credited to your fix.
  4. 4 I fix it, harden it, and prove it live with real transactions before we're done.

What's included — and what's not

diagnosis plus flat-price repair of the broken store (WooCommerce, Shopify or custom)
checkout/payment, error, security and data-integrity fixes
a written summary of what was wrong and what I changed
the fix proven live before handover
building a brand-new store from scratch (separate project)
ongoing changes or new features unless on a care plan
naming and shaming the previous dev or tool — I just fix it

Flat pricing — you approve a number, not a meter

Every rescue starts with the paid 48-hour triage, credited to your fix. You approve the flat fix price before I start the repair.

Fixed-price fix

Full repair of your AI-generated or broken store — production 500s, broken checkout, security holes — quoted as one flat number after triage.

$2,500–$6,500 flat

48-hour triage — first step, credited

I reproduce the failure, scope the damage, and send a written plan plus a flat quote.

$690 (credited to your fix)

Care plan (optional, ongoing)

Keep the store stable and monitored after the fix.

$190 / $390 / $690 per month

You approve a single flat fix price before any repair work starts — never an open-ended hourly bill. The 48-hour triage is paid (you get a real written diagnosis and plan) and is credited in full toward the fix. If I genuinely can't diagnose the problem, I'll say so rather than guess on your dime.

A senior engineer who ships production code, not prompts

I'm Marc Stan — 6+ years shipping production full-stack (React, TypeScript, .NET, PHP), 125k+ lines of real WooCommerce/PHP, and the operator of a store doing 100–150K visits a month. I've spent my career on exactly the parts AI gets wrong: payments, concurrency, security — things that only break with real money on the line. I prove every fix live.

  • 6+ years production full-stack; 125k+ LOC WooCommerce/PHP
  • I run a real store at 100–150K visits/mo — I live in production
  • Deep on the failure-prone parts: payments, security, data integrity
  • Every fix proven live before we call it done
Real result on a store I run: admin response cut from 3,000ms to 400ms.

Limited rescue slots — it's me, not a queue

  • A few concurrent rescues so triage stays inside 48 hours
  • Down in production right now? WhatsApp for a same-day look
  • Every hour a broken store is live is orders and trust you don't get back

Questions before you book

Do I need to know what's wrong?

No — that's the triage. You give me access; I find it.

What if it's cheaper to rebuild than fix?

If the triage shows that, I'll tell you honestly and scope the smallest viable path. I'm not here to bill the biggest job.

Will you work with code an AI wrote?

Yes — most of my rescue work is exactly that. I don't care who or what wrote it; I make it work and make it safe.

Is the triage refundable?

The triage is paid work — you get a real diagnosis and plan — and it's credited to your fix. If I can't even diagnose it, I won't string you along.

How fast?

Triage in 48 hours; most fixes 1–3 weeks depending on scope.
