AI-built application review · Stacknyu

An AI-built demo is a start. Find out what it needs to ship.

For founders commissioning engineering work on an existing AI-built application. Show us what works, what fails and who will use it. We can assess the code and release risks, then scope the work rather than promise that every project is one quick fix away.

  • An engineering engagement, not a prompt tool
  • Review the code before committing to a repair
  • Retain, rework or rebuild based on evidence

The work

Engineering beyond the first working screen.

These are examples of platforms we built and operate, not claimed AI-code rescue case studies. They show the kinds of roles, workflows and integrations a release needs to account for.

Your next build

Start with the part that is blocking the product.

The review determines what can be retained, what needs work and what may not be economical to repair.

Review the existing application

Inspect the application structure, reported failures and deployment setup to establish what is known and what still needs investigation.

Discuss this project

Scope the missing engineering

Discuss access control, data handling, integrations and broken workflows as specific deliverables, not a blanket promise to fix everything.

Discuss this project

Plan a testable release

Agree the critical user journeys, test scope, deployment steps and remaining limitations before calling the application ready.

How we start

Understand the code before promising the outcome.

Discuss the application

  1. Describe the current state

    Share the application purpose, technology if known, failing user journeys and a public demo if available. Do not paste credentials into the form.

  2. Arrange an appropriate review

    Agree access and review scope separately. Compare targeted repairs with partial or full rebuilding where the existing structure creates risk.

  3. Agree the next delivery scope

    Set acceptance criteria, responsibilities and a release plan for the work you choose to commission. A review does not certify the whole application.

Let's make it real

What is stopping the application from moving forward?

Describe the business use case, what works, what fails, the technology if known and your role in the project. Include a public demo only if it is safe to share. Keep credentials and private customer data out of this form.

Fields marked * are required.

Project enquiry

Include your currency if you have a range in mind.

We use these details to respond to your enquiry. Please do not include passwords or confidential customer records.

For owners preparing a real application for users.

Good fit

  • You own the project or are authorised to commission work on it.
  • There is a defined business use case and willingness to fund engineering work.
  • You can provide appropriate code access after agreeing how the review will work.

Not a fit

  • You want free debugging, more AI prompts or a tutorial rather than a development engagement.
  • You need a guarantee that unseen code can be repaired without a rebuild.
  • You cannot authorise access to the code or the work being requested.

Before you enquire

Questions & answers

Can you guarantee that the existing project can be fixed?

No. The code, dependencies, data model and intended use need review. Targeted repairs may be sensible; in other cases, rebuilding a part is more practical. We explain the trade-offs before agreeing the work.

Does production-ready mean the application is certified secure?

No. Review and testing cover an agreed scope. Security requirements, sensitive data, specialist audits and residual risks need explicit discussion; no blanket security certification is implied.

What should I send in the first enquiry?

Describe the product, the blocked workflow, the stack if known and what has already been tried. A public demo can help. Do not send API keys, passwords, customer data or private repository credentials through this form.

Can you quote before seeing the code?

We can discuss the problem and possible engagement, but a reliable repair scope may require a code review. We do not promise a fixed price or completion date for an application we have not assessed.
