App review, technical help, and development

Built an app with AI? We help you take it further.

Have a prototype, a working app, or a change you're unsure about? We review the code, fix issues, and help implement new features. You can keep working with AI — you don't need to hand over the whole project.

You don't need to know the cause of a problem before you write to us.

Project review, a specific problem, or further development?

You want to review the project

Your app works, but you're not sure what to check before making it available to customers? We review the agreed areas: behavior, code, data access, and readiness for launch.

Outcome You know what works, what needs fixing, and in what order to address it.

You're stuck on a specific problem

Sign-in does not work, an integration returns errors, or the next fix breaks something else? We identify the cause and implement the agreed solution. We can work on one part without taking over the whole app.

Outcome The problem solved, and an explanation of what changed.

You want to keep developing the product

Need new features, integrations, or support with future changes? We can develop the app or support you and your team through consultations and code reviews.

Outcome A plan for the next steps and support in carrying them out.

We look at the code and how the whole app works.

We match the scope to your goal. Help with one issue does not have to mean a full review.

  • Do users have access only to their own data?

    We check sign-in, roles, and access rules — including what is not visible on screen.

    Technical details

    API authorization, data separation, record permissions, and secrets.

  • What happens when something does not go as planned?

    We verify agreed scenarios, such as an interrupted payment, a form submitted again, or an external system that is unavailable.

    Technical details

    Validation, error handling, integrations, and webhook retries.

  • Do later changes break earlier ones?

    We look for the causes of recurring issues and areas that make development harder. We help organize the code and select the tests that are needed.

    Technical details

    Code review, architecture, dependencies, tests, and database migrations.

  • Can the app be deployed and maintained?

    We help move from a local version to deployment and review performance, configuration, backups, and error logging.

    Technical details

    Environments, CI/CD, monitoring, and database queries.

The review covers the agreed scope. It is not automatically a full penetration test and does not guarantee that all bugs will be found.

You know what to do next — not just what is wrong.

After the agreed review, you receive specific findings: where we found an issue, its impact, and what we recommend. We separate urgent fixes from changes that can wait. We also state the limits of the analysis and areas that need further review.

You can then decide whether to proceed on your own, with your team, or with our help. We estimate further work after agreeing the scope.

Sample action plan
  1. When: Before launch

    Action: Restrict access to other accounts' data

    How we check: Permission test

  2. When: Next stage

    Action: Speed up product search

    How we check: Database query measurement

  3. When: Later

    Action: Clean up duplicated code

    How we check: Review and tests

Illustrative example. Priorities depend on the specific app.

First, we agree what you need. Then we work on the project.

  1. 1

    You describe the situation

    Tell us what you are building, what already works, and where you need help. A written description or a link to the app is enough to start.

  2. 2

    We agree the scope and cost

    Whether it is a consultation, a review of one area, or larger work, we match the form of help to the problem.

  3. 3

    We deliver the agreed stage

    An analysis ends with findings and recommendations, while agreed fixes include changes and a check that they work. You decide whether to continue.

You work directly with the specialist responsible for your project. We combine work on code, integrations, and infrastructure, so a diagnosis does not end with saying that the problem lies somewhere else.

Frequently Asked Questions

I am not a developer. Can you help?

Yes. Describe what the app does and what you need help with. We will help identify the information that is needed. You do not need to arrive with a technical diagnosis.

I am a developer. Can I ask for only a code review or help with one problem?

Yes. The scope can cover a selected change, integration, performance issue, or architecture decision. You do not need to order a full review or hand over the whole project.

Can I keep developing the app on my own with AI?

Yes. If you are building through “vibe coding” or with an AI assistant, you can keep working that way. We can discuss ideas, review important changes, and help with more difficult parts. You remain in charge of the project.

Will the app need to be rewritten from scratch?

We do not assume that. We first assess the existing solution. If a larger rebuild is justified, we explain why and discuss the options before work starts.

How much does help cost, and is the first conversation paid?

A brief introductory exchange — a few messages, or a short call if you prefer — is free. Technical consultation, code analysis, and development work are paid. We agree the scope and cost before work starts.

Do I need to share the code publicly or provide production access?

No. A project description is enough to start. If the analysis requires code or an environment, we agree how to share it and the access that is needed. Do not send passwords, API keys, or user data through the contact form.

Show us what you have. Let's decide what makes sense next.

Describe what you are building, what already works, and where you need help. You can include a link to the app or repository, but it is not required.
