AI-Built App Not Working?
Turn a promising prototype into an application your business can use. I diagnose broken functionality, repair the underlying code and help prepare your app for production.

From the problem to a practical fix
Features break after every change
Trace failures across the interface, backend and database. Repair the cause and add regression tests around the workflows your users rely on.
Integrations work only in the demo
Review API calls, authentication, payments and error handling. Make failures visible and define how the application should recover.
Deployment is blocking your launch
Investigate build failures, environment configuration and release steps. Establish a repeatable deployment process with checks and a rollback plan.
The app feels slow or hard to trust
Review bottlenecks, access controls and exposed secrets within the agreed scope. Simplify fragile code so the next change is easier to maintain.
How we work together
Describe the blocker
Share what the app should do, what fails and your launch constraints. Start with a description; do not send credentials or customer data.
Agree a focused review
We define access, scope, price and timing. I reproduce the issue and identify the dependencies that affect the repair.
Repair and verify
After you approve the plan, I implement the agreed fixes and check the affected user journeys in a suitable test environment.
Prepare the handover
You receive the changes, verification notes and remaining risks. Production deployment and ongoing support are agreed separately.
What you take away
- A diagnosis with prioritized fixes
- Reviewed code changes for the agreed repair scope
- Tests and verification notes for affected workflows
- Deployment guidance and a list of remaining risks
Experience with the systems behind the screen
Built with Lovable, Bolt, Cursor, Claude Code or another AI development tool? The generated code and infrastructure determine the work. Opcode’s existing services cover React, APIs, databases, cloud infrastructure and production troubleshooting. Stack fit is confirmed before an engagement.
You work directly with Jacek Różański, software developer and architect. The first step is understanding your system and the business decision it needs to support.
Questions before you start
Can you work on an app built with an AI tool?
Yes, provided the source code and relevant configuration can be reviewed. Share the tools and stack you use; I confirm whether the application fits my expertise before agreeing the work.
Will you need to rebuild the whole app?
Not by default. I first assess whether targeted repairs are practical. If a component needs replacing, you get the reasons and options before implementation.
How much will the repair cost?
The scope, price and timing depend on the issue and the state of the application. We agree the initial review first, then a repair plan before making changes.
Can you guarantee it is ready for production?
No review can guarantee a failure-free application. The handover identifies what was tested, what remains uncertain and which issues should be addressed before release.
Get Your App Reviewed
Tell me what your application does, what is getting in the way and what you need to achieve. I will reply with the information needed to agree the next step.
Please do not include passwords, API keys or customer data. Repository access can be arranged after we agree the scope and confidentiality requirements.
