The gap

Your MVP works. That doesn't mean it's ready.

AI tools got you from idea to working product in days. That's real progress. But a demo only has to work once, for you. Production has to work every time, for everyone — including people trying to break it.

What you've already proven

AI-built MVP

  • WorksYes
  • Ships fastYes
  • Impressive demoYes

Tested by: you, on the happy path.

What real users need

Production software

  • SecureUnverified
  • ReliableUnverified
  • ObservableUnverified
  • RecoverableUnverified
  • MaintainableUnverified

Tested by: real users, real traffic, and people trying to break it.

Most founders can't tell which of these their app actually is. A production-readiness review answers that — with evidence, not guesswork.

Pro-AI. Pro-production.

AI changed how software gets built. It didn't change what production software requires.

CairoBits isn't anti-AI — AI-assisted development is part of how we work. It makes building an MVP dramatically faster.

But the moment real users sign up, the old fundamentals are back. AI tools tend to optimize for “it runs”. Production needs more than that.

CairoBits exists in that gap.

Production still requires

  1. 01Secure authentication
  2. 02Correct authorization
  3. 03Robust data handling
  4. 04Reliable infrastructure
  5. 05Observability
  6. 06Deployment discipline
  7. 07Testing
  8. 08Failure handling
  9. 09Sane architecture

What we do

Two ways in. One standard.

The code either exists already or it doesn't. Either way the destination is the same: software that holds up with real users, real money and real data behind it.

You already built it

Productionize

Make what you shipped safe to run.

We review the application, codebase and infrastructure against a production-readiness standard, then fix what matters — highest severity first, with you deciding what stays in scope.

  • Production-readiness review, with prioritized findings tied to specific code
  • Critical and high-severity issues fixed first
  • Authentication, permissions and data access hardened
  • CI/CD, environments, monitoring and backups set up
  • Tests around the paths that would hurt to break

For apps built with AI tools or by hand, where nobody has checked what's underneath.

You have it in mind

Build

Start it right instead of rescuing it later.

We build it with AI-assisted engineering: the speed you would get from a prototype tool, with the architecture, security and operations of software that is meant to last.

  • Architecture and data model designed before the code
  • Auth, permissions and payments built properly the first time
  • Infrastructure as code, CI/CD and real environments from day one
  • Logging, error tracking and recovery in place at launch
  • A codebase your team — or your AI tools — can keep working in

For a prototype, an MVP or a first production release you won't have to rebuild in six months.

How pricing works

  • Scoped on a free call

    Thirty minutes to understand the work before anyone talks money.

  • Fixed price, in writing

    Scope, price and timeline agreed up front. Nothing is charged until you accept it.

  • Never hourly

    No open-ended retainers and no meter running while you think.

Every engagement is scoped differently, so prices aren't published.

What we check

We look underneath the hood.

Twelve areas where apps look fine in a demo and fail under real users. We review them in an app you already built, and build against them in one we write for you.

  • SEC01

    Security

    Secrets, input validation, injection risks and exposed attack surface.

  • AUTH02

    Auth & Permissions

    Can users only see and change what they're allowed to? Sessions, roles, tenant isolation.

  • ARCH03

    Architecture

    A structure that survives the next ten features — not just the last ten prompts.

  • DATA04

    Database

    Schema design, indexes, migrations, constraints and data integrity.

  • API05

    APIs

    Contracts, validation, error responses, rate limits and abuse cases.

  • PERF06

    Performance

    Slow queries, N+1s, bundle weight and behaviour under real traffic.

  • TEST07

    Testing

    Whether critical paths are covered — and whether the tests actually test anything.

  • DEPS08

    Dependencies

    Vulnerable, abandoned or unnecessary packages, including ones your AI tool added.

  • INFRA09

    Infrastructure

    Hosting, environments, configuration and least-privilege access.

  • CI/CD10

    CI/CD

    Repeatable builds, safe deploys and a way to roll back.

  • OBS11

    Observability

    Logging and error tracking, so you hear about failures before your users do.

  • REL12

    Reliability

    Error handling, backups, recovery and what happens when something upstream fails.

This is a production-readiness engineering review, not a formal penetration test.

The deliverable

You don't get a vague code review. You get a prioritized action plan.

Every productionize engagement starts here: know what must be fixed before launch, and what can safely wait. Each finding is specific enough to act on — whether we do the fixing, or you, your team or your AI coding tool do.

01Severity
How urgent it is, on a four-level scale.
02Explanation
What's wrong, in plain language.
03Evidence

  • Severity: CriticalCB-001 · Fix before launch

    Broken authorization on project endpoint

    The endpoint checks that a user is signed in, but not that they own the project they're requesting.

    Evidence api/projects/[id]/route.ts — query filters by id only

    Why it matters

    Any signed-in user can read another customer's data by changing the ID in the URL.

    Recommended fix

    Scope the query to the session's organization and add a cross-tenant access test.

  • Severity: HighCB-002 · Fix before launch

    Production secrets exposed through environment handling

    A privileged database key uses a public env prefix, so it's bundled into client-side JavaScript.

    Evidence NEXT_PUBLIC_DB_SERVICE_KEY referenced in lib/db.ts

    Why it matters

    Anyone can extract the key from the browser and bypass data-access rules.

    Recommended fix

    Rotate the key, move privileged access server-side, and use a restricted key in the client.

  • Severity: MediumCB-003 · Fix soon

    Missing error boundaries

    One failed request blanks the entire dashboard, and the error isn't reported anywhere.

    Evidence No route-level error handling; no error tracking configured

    Why it matters

    Users hit dead screens and you have no signal that anything went wrong.

    Recommended fix

    Add route-level error boundaries with a recovery action and connect an error tracker.

  • Severity: LowCB-004 · Can safely wait

    Dependency cleanup

    Unused packages and two overlapping date libraries remain from earlier iterations.

    Evidence package.json — 11 unused dependencies

    Why it matters

    Larger bundles and more packages to keep patched. Not a launch risk.

    Recommended fix

    Remove unused packages and standardize on one date library.

Who reviews your app

Built by someone who's been on the other side.

Built for production because I've built for production.

I've spent the last 9+ years building and leading production software — from architecture and infrastructure to deployment, reliability and engineering processes. As a founding engineer, I've owned systems from zero to production, including cloud infrastructure, CI/CD, identity, payments and distributed systems.

I also use AI-assisted development with Claude Code in production. I know first-hand how quickly AI can turn an idea into a working product — and where that speed can leave engineering gaps behind.

  • Founding engineer at Rentinit — owned every technical decision for a rental management platform built from the ground up on React, TypeScript, .NET 9 and PostgreSQL on Azure.
  • Designed payment and escrow flows: bank account linking, IBAN validation and automated disbursements.
  • Integrated UAE PASS digital identity using OAuth2 and Duende IdentityServer.
  • Automated infrastructure with Azure Bicep; built CI/CD, preview environments and a dev → test → UAT → pre-prod → production → DR pipeline.

FAQ

Questions founders ask first.

Anything else? Ask on the intro call.

What kind of work do you take on?

Two kinds: making an existing application production-ready, and building a new one with AI-assisted engineering. Usually early-stage SaaS products and startup MVPs.

Do I need to have built something already?

No. If you have an idea and no code, the call is about what to build and what production-ready means for it. If you already have an app, the call is about what's in it.

What does the intro call cost?

Nothing. It's 30 minutes, and you leave knowing what we would do — whether or not you hire us.

How much does an engagement cost?

It depends entirely on scope, so prices aren't published. You get a fixed price in writing after the call, and nothing is charged until you accept that quote.

Do you bill hourly?

No. Engagements are fixed-scope and fixed-price, so you know what you're paying before the work starts.

Do I need to be using AI?

No. AI-built applications are the primary focus, but the same engineering applies to anything built by hand.

Is this a penetration test?

No. A production-readiness review is an engineering review, not a formal penetration test or certification. It will surface real security problems in your code and setup, but it isn't a guarantee of security.

What do you need from me?

For an existing app: read-only access to the repository and a link to the deployed application. You don't need to share production credentials. For a new build: whatever you have — notes, a sketch, a prototype, or just the problem you're solving.

Before real users find the cracks, find them first.

Whether it is already built or still an idea, start with a free thirty-minute call and a fixed-price quote.
