I will diagnose and fix PHP, javascript, HTML or CSS bugs
Pierre-emmanuel
About this gig
Is your website showing an error or behaving in a way that makes no sense?
I will investigate the problem before modifying the code, identify the likely root cause and implement a clean fix whenever possible.
I can work with PHP, JavaScript, HTML, CSS, MySQL and SQLite on existing websites and web applications.
Typical issues include PHP errors, broken forms, JavaScript problems, layout bugs, database-related errors and unexpected behavior after a modification or migration.
I work carefully with existing code and avoid unnecessary rewrites.
For complex or unclear issues, please contact me before ordering.

FAQ
What information do you need before starting?
Please describe the problem, what you expected to happen, what actually happens, and any recent changes made to the website. Screenshots, error messages and reproduction steps are very helpful.
Should I contact you before placing an order?
For simple and clearly identified issues, you can order directly. If the problem is intermittent, affects several parts of the application or its cause is unknown, please contact me first so I can evaluate the scope.
Can you work on an existing or older PHP website?
Yes. I can work with existing PHP, JavaScript, HTML and CSS codebases. I prefer to understand the current structure before modifying it rather than unnecessarily rebuilding working parts.
What happens if the bug is caused by another service or the hosting environment?
I will identify the likely cause and explain it clearly. If the solution depends on a third-party service, plugin, API or hosting provider outside the agreed scope, I will tell you what needs to be done before proceeding further.
Do you guarantee that every bug can be fixed?
I guarantee a serious diagnostic and work within the agreed scope. Some problems can depend on inaccessible third-party systems, obsolete software or hosting restrictions, so I do not promise a fix before the cause has been identified.
