Sign-in and data permissions
Sign-in returns to the wrong screen, data is not saved or accounts can see each other’s records. Reproduce the issue and inspect access and data flows.
Software development for Hong Kong SMEs
The AI built the screens. Now complete the working flows.
Built an app or website with AI but stuck on sign-in, payments, data or deployment? ProApp provides AI code rescue and Vibe Coding takeover for Hong Kong SMEs: reproduce the problem, review code and deployment, identify reusable parts, then complete the agreed flow.
What can we help you build?
Payments and service activation
Check payment events, order status and service access, including duplicate notifications, cancellations and failed steps.
Deployment and maintainability
Review code, configuration, databases and external dependencies, check deployability, and set a repair and handover sequence.
Agree the scope before development begins.
The following work can be discussed. Included features, deliverables, fees and scheduling are agreed for your project.
- Confirm source code, platform and account access, then reproduce specified issues in a suitable environment.
- List reusable parts, critical issues and priorities; detailed assessment and repair can be separate stages.
- Repair agreed sign-in, payment, data or deployment issues and run regression checks on related functions.
- Provide change and test records, known limitations, deployment information and maintenance notes.
Estimate fees and scheduling around this scope.
What affects the quotation?
- Code/account access, documentation and the current technology and deployment state.
- Issue reproducibility, affected scope and the choice of repair, partial rewrite or redevelopment.
- Related functions to check, test accounts, release constraints and handover work.
Assessment, development and handover
An initial discussion of requirements is free. Detailed assessments have an agreed scope and fee; development or repair specifies included features, tests, deployment and handover. Hourly work, fixed quotations and ongoing support follow the current pricing information and your agreed proposal.
Ongoing and third-party costs
Review current hosting, databases, AI or other APIs, paid tools, store accounts and subscriptions. Repair quotations do not automatically include these recurring fees. Ongoing maintenance, updates and fault support are agreed separately.
See pricing and engagement optionsHow will completion be checked?
Start with a previously failing flow and compare results using test accounts, then check other roles, invalid inputs and retries. Production readiness is assessed against agreed functions, deployment conditions and unresolved issues.
What should you share in your first enquiry?
- A public URL or error screenshots and the AI tool or platform used.
- The most disruptive failing flow and how it should work.
- Whether you have source code, deployment and database access; do not send passwords in your first enquiry.
Questions about this service
Does AI-generated code need a complete rewrite?
No. We review the code, data structure and deployment to identify reusable parts and risks, then compare repair, partial rewriting and redevelopment.
Can you assess a project without source code?
Share the platform, URL and available account access first. Inspection and changes depend on export, access and deployment restrictions. Work is arranged after confirming what is feasible.
Can I enquire before I have a specification or budget?
Yes. Describe the users, the problem and your target date. ProApp will outline a workable scope before confirming an estimate and scheduling. If a detailed assessment is needed, its work and fee are explained first.
How are handover and support arranged?
The proposal specifies source code, deployment, account ownership, operating instructions and acceptance checks. Ongoing maintenance, third-party subscriptions or usage fees and support hours are agreed for the project.
