App review, technical help, and development
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.
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.
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.
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 match the scope to your goal. Help with one issue does not have to mean a full review.
We check sign-in, roles, and access rules — including what is not visible on screen.
API authorization, data separation, record permissions, and secrets.
We verify agreed scenarios, such as an interrupted payment, a form submitted again, or an external system that is unavailable.
Validation, error handling, integrations, and webhook retries.
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.
Code review, architecture, dependencies, tests, and database migrations.
We help move from a local version to deployment and review performance, configuration, backups, and error logging.
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.
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.
When: Before launch
Action: Restrict access to other accounts' data
How we check: Permission test
When: Next stage
Action: Speed up product search
How we check: Database query measurement
When: Later
Action: Clean up duplicated code
How we check: Review and tests
Illustrative example. Priorities depend on the specific app.
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.
Whether it is a consultation, a review of one area, or larger work, we match the form of help to the problem.
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.

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.
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.
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.
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.
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.
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.
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.
