Razoyo | Hardening a Vibe-Coded App for Production

AI-Built Prototypes · Production Hardening · We Take Over Unfinished Work

The Prototype Works On Your Laptop. That Is Not The Same As Working.

An AI tool can get you to a working demo fast. Getting from demo to something that survives real users, real data and real load is a different job, and it is the job most AI-assisted builds stall on. Razoyo evaluates what actually exists and gives you a straight answer: harden it, or rebuild it.

We used an AI tool to get to a working demo fast. Now what?

Someone else started building this and we need a second opinion.

We do not know if this needs three fixes or a full rebuild.

We are worried about being locked in to whoever finishes it.

Short Answer: The Tool That Built It Matters Less Than You Think.

Whether a prototype came from an AI tool, a freelancer, or an agency that started and stalled, the evaluation is the same: can the existing system carry production load, and how much of it is worth keeping. Razoyo's System Spec is a fixed-price, time-boxed engagement that answers that question before you commit to a rebuild you may not need, or a patch job that will not hold.

What a fast build typically has not had time to earn

The pattern, not a judgment

What "Vibe-Coded" Usually Means By the Time It Reaches Us.

This is not about the tool. It is about what a fast build typically has not had time to earn.

It was built to demo, not to hold

The happy path works. Edge cases, bad input and concurrent users were never the test.

The data model was never designed, it accreted

Fields got added as the demo needed them, not as the domain required them.

Nobody who understands it end to end is still around

Or nobody ever fully did.

There is little or no test coverage

Every change risks breaking something nobody knew depended on it.

None of that means the work has to be thrown away. It means someone has to actually look before deciding.

The real screening question

Why the Stack It Was Built In Matters Less Than the Question It Raises.

The question a buyer is actually asking is not "can you write code in the tool I used." It is "can you take over something you did not build and tell me honestly what state it is in."

A different skill from greenfield development

What it is not

Whether you can write code in the tool that built it
Whether the starting point was an AI builder, no-code platform, or a stalled team

What it actually is

Can you take over something you did not build
Will you tell the client honestly what state it is in
Is that skill different from greenfield development

That is a different skill from greenfield development, and it is the one that matters here regardless of how the first version got built.

We Have Done This Before, Regardless of How It Started

Hello Vector / Stars

A digital agency proposed a plan, started the build, and did not have the depth to finish customising the platform the way the project needed. Razoyo took it over and finished it. The failure mode is the same whether the half-finished work came from an agency or an AI tool: work started, then stalled, and someone has to evaluate what exists before deciding whether to continue it or replace it.

How the work actually runs

You Approve the Effort Before Anyone Writes Code.

The reason projects overrun is almost never a surprise in the code. It is that nobody agreed what a piece of work was worth before it started.

How the Work Actually Runs

Every item gets an estimate first

A business analyst puts a level of effort and a budget on each piece of work, and we get your confirmation before touching it.

You watch the same board we do

Access to our project management system. Re-order it whenever you want, or tell us to stop.

The budget stops itself

We work to the monthly number and tell you when we hit it.

Three layers of testing on every change

Code, acceptance and regression testing, then again after it goes live.

You approve it on staging first

Every change lands on a private environment before it touches production.

Something breaks at 2am

There is an emergency line and a published rate for it.

Retainers run month to month. Thirty days notice to stop, fifteen to change the budget.

A fixed-price System Spec, yours to keep

Define it properly first

That Is Where Projects Are Won or Lost.

Most software projects do not fail because the code does not work. They fail because the product was poorly thought out. So reduce the ask from "commission a project" to "find out."

System Spec

Start here

$2,500 fixed · yours to keep

Time-boxed

We evaluate the running system, the data model, and where it breaks under load, and hand you a written brief, a number, and a straight harden-or-rebuild call.

A product brief and PRD you own outright
A senior-engineer build estimate
A documented harden / rebuild call
Yours to keep, even if you build with someone else

Book a System Spec

Free Consultation

Free 1 hour · no obligation

Bring what exists today. You'll leave knowing whether it is worth a System Spec and what it would take, before you spend a dollar.

A senior person, not a sales rep
A straight answer on harden vs. rebuild
A scoped next step and what it costs

Schedule Free Consultation

The System Spec is yours outright, take it to any team. You own the code, the repo, and the infrastructure, always.

Questions We Get Before the Call

Less than you would think. What we evaluate is the running system: what the data model actually is, where it breaks under load, and how much of the domain logic is worth preserving. That evaluation does not depend on who or what wrote the first version.

It is an engineering question with a real answer, and it is what the System Spec exists to determine. We look at where the system actually breaks under real load, how sound the data model is, and what it would cost to reach your next stage on the current architecture versus starting over.

It is the normal case, not the hard one. Most of what we need is in the code, the data and the infrastructure itself. What we need from you is the business context: what the system is supposed to do, and what breaks most often.

We evaluate the running system and the data model underneath it, not the specific tool that produced it. If a particular platform has constraints that affect the harden-or-rebuild decision, that comes out during the Spec, not before it.

Then that is what we will tell you, and the Spec has still paid for itself. We are not incentivized to recommend the bigger job: the Spec is fixed price either way.

Pick your next step

Start With a Conversation. It Costs Nothing.

Every engagement begins the same way, with a free consultation. You will leave it with an honest recommendation, including the recommendation not to build.
