Rescue Engineers
Your AI built the demo.
We build the company.
Senior engineers who secure, finish, and scale the apps AI helped you build. Diagnostic in days, not months.

AI closes 80% of the distance. The last 20% is where companies get built, or quietly break.
Vibe coding is genuinely incredible for getting to a working demo. But a demo and a business are different things, and the difference is exactly the part AI is worst at: security, data integrity, scale, and the boring rigor that keeps a product alive once real people and real money are on it.
It looked done. It wasn't safe.
The app demoed perfectly, so nobody checked whether the database was wide open. Independent scans keep finding the same thing: the polish hides missing fundamentals like access control and key management.
Then real traffic arrived.
Built for a screenshot, not for scale. The first spike in users surfaces N+1 queries, no caching, no indexes, and a data model that was never meant to hold a business.
And someone asked to look under the hood.
An investor, an acquirer, or a serious customer wants a technical review, and "I don't really know how it works" becomes the most expensive sentence a founder can say.
The numbers on AI-built code aren't reassuring.

Six ways an AI-built app goes wrong. One team that fixes all of them.
Every engagement starts with a diagnosis, then we scope exactly what you need, nothing you don't.
Security & hardening
Exposed keys, disabled row-level security, unauthenticated endpoints. We find what's open, close it, and prove it's closed with a scorecard.
Finish the build
Stuck at 80%, the last bug the AI keeps going in circles on. We finish it properly and get you to a launch you can stand behind.
Takeover & handoff
Your freelancer vanished or your no-code developer hit their ceiling. We read the codebase, document it, and become the team you should have had.
Scale & rebuild
It buckles under real users. We fix the data model, add caching and indexes, and migrate you off the no-code ceiling onto a stack that holds.
Due-diligence readiness
A term sheet is contingent on a technical review. We produce the scorecard, architecture review, and remediation plan you can hand to their engineers.
Ongoing engineering
Once it's stable, we stay on as your fractional engineering team, so the next feature doesn't start the fire all over again.
A calm, senior process, on an emergency's timeline.
Triage
A senior engineer reads your actual code and infrastructure. We tell you what's on fire, what's fine, and what it will take, in plain English.
Diagnose
A full diagnostic: security scorecard, architecture map, and a prioritized findings list. This is the deliverable you can show an investor.
Stabilize
We stop the bleeding first, close the critical security holes, recover data integrity, and get you a system that won't fall over tonight.
Rebuild & hand back
We harden, scale, and document, then hand you a codebase you own, with the option to keep us on as your engineering team.
Not another AI-hype shop. Real senior engineers with over a decade behind them.
Rescue Engineers is a senior-only engineering team with over a decade shipping production software, including Shopify apps and custom applications for real businesses with real revenue on the line. We have read a lot of code we didn't write. That's the whole job.
- Senior engineers only. No offshore junior pool, no hand-off to someone who's never opened an AI-generated repo.
- Not afraid of AI. We adopted it completely. We just knew what we were doing before AI existed, which is why we're lean enough to run a diagnostic in days and stabilize a broken app in weeks, not months.
- We fix, we don't lecture. We keep what works and repair what doesn't, instead of billing you to rewrite your own product.
- Fixed scope, fixed price. You'll never be billed into an open-ended hole. Every engagement has a defined outcome.
- You own everything. Your code, your infrastructure, your accounts. We hand back the keys and full documentation.

Representative example of a diagnostic-to-handoff scorecard. Not a specific client.
If any of this sounds like you, it's not too late.
"An investor wants to see the code, and I'm not sure what they'll find."
You raised on a great product. It's ~95% AI-generated and diligence is in two weeks. We get you a clean bill of health, or a credible plan to one, fast.
"I already paid someone $15k. Now it's broken and they're gone."
You believed in the product enough to pay for it once. We're the team that actually finishes the job, on a fixed scope, with references you can call.
"It worked in the demo. Now it's breaking and I can't read the code."
You have real users on a foundation you don't fully understand. We make it solid without making you feel dumb about how you got here.
A market of hidden quotes and Fiverr gambles. We just tell you.
Real ranges, so you know where you stand before the first call. Final scope is set after the diagnostic.
An async scan and a written findings report in days. Credited toward the full audit if you go ahead.
Security scorecard, architecture review, prioritized findings. The document you hand an investor.
Close the critical holes, stabilize, and get to a production-ready, secure app.
Migrate off the no-code ceiling, rebuild for scale, and take over as your engineering team.
The things founders ask us first.
Will you rewrite my whole app?
No. We fix what's broken and keep what's working. A full rewrite is a last resort we only recommend when the foundation genuinely can't be made safe, and we tell you that plainly, before you spend a dollar on it.
How fast can you start?
Triage usually begins within 24 to 48 hours. If you're actively down or exposed, tell us in the first message and we'll treat it as an emergency.
Can you get me through investor technical due diligence?
Yes. We produce a security scorecard, an architecture review, and a remediation roadmap written to be handed directly to an investor's technical partner, and we remediate the blocking issues on a diligence timeline.
My developer disappeared. Can you take over what they left?
Yes, that's a core service. We read and document the existing code, stabilize it, and become the engineering team you should have had, on a fixed scope so you're never billed into an open-ended hole again.
Who actually does the work?
Senior engineers only. The team has spent over a decade shipping production software, including Shopify apps and custom applications. No offshore junior pool.
Send us the repo. We'll tell you the truth about it.
Start with a $1,500 Rapid Diagnostic. A senior engineer reads your actual code and sends back a written assessment: what's on fire, what's fine, and what it takes to fix. The fee comes off the full audit if you go ahead. No sales engineer, no junior.
