I will fix and stabilize your PHP mysql saas application
Phuc Nguyen
About this gig
If your PHP or MySQL application is failing, unstable, or behaving incorrectly, I will trace the issue to its root cause and fix the relevant code safely.
I work on existing SaaS products, business applications, APIs, authentication flows, databases, admin systems, and custom PHP applications.
Typical issues I can help with:
- PHP errors, exceptions, and broken logic
- MySQL queries, data persistence, and database issues
- API and third-party integration failures
- Authentication, sessions, roles, and permission bugs
- Forms, CRUD operations, and backend/frontend data flow
- Performance problems and slow queries
- Broken workflows involving multiple application layers
- Existing Laravel, CodeIgniter, Symfony, or custom PHP codebases
My goal is not to hide the symptom. I inspect the affected flow, identify the cause, fix the relevant code, and verify that the change does not break adjacent behavior.
Please message me before ordering if the issue affects multiple modules or the exact scope is unclear.

FAQ
What do you need from me to start?
A clear description of the issue, steps to reproduce it, relevant screenshots or error messages, and access to the affected source code or environment when required.
Can you work on an existing or legacy PHP application?
Yes. I can work with existing custom PHP applications and common PHP frameworks without requiring a full rewrite.
Do you fix database and API issues as well?
Yes. I can trace issues involving PHP, MySQL, REST APIs, authentication, permissions, and related application logic.
What counts as one bug for the Basic package?
One clearly defined issue with a reproducible symptom and a focused scope. If several modules or unrelated problems are involved, I will recommend the appropriate package or a custom offer.
Will you rewrite my whole application?
No. This Gig is focused on fixing and stabilizing existing functionality. Larger rebuilds, new modules, or major architecture changes should be handled through a custom offer.
