I will fix backend errors in PHP node js API and database issues
lotto mallik
About this gig
Your site throwing errors, your API failing, or your database acting up? I debug and fix backend issues in PHP, Node.js, REST/API integrations, and database problems (MySQL, PostgreSQL, MongoDB) so your application runs smoothly again fast.
What you get:
- Diagnosis and fix of PHP errors (fatal errors, warnings, deprecated functions, plugin/framework conflicts)
- Node.js backend debugging (crashes, unhandled exceptions, async/performance issues)
- API troubleshooting (broken endpoints, authentication errors, failed third-party integrations)
- Database issue resolution (slow queries, connection errors, data integrity problems, migrations)
- Clear explanation of the root cause, not just a patch
Why work with me:
I don't just silence the error I find what's actually causing it so it doesn't come back. I work across PHP (including WordPress/Laravel), Node.js, and SQL/NoSQL databases, so I can trace issues that span your full backend stack, not just one layer.
Send me the error message, relevant code/logs, or access details, and I'll take a look message me first for anything urgent or complex.

FAQ
What information do you need to start?
The exact error message, relevant code snippets or logs, and access to your server/repo/database (or a staging environment) if the issue can't be diagnosed from code alone.
Can you fix urgent/live-site issues fast?
Yes, message me first with the issue and I can quote rush delivery depending on complexity and current availability.
Do you need full server access?
Only if the issue requires it. For many bugs, code and logs are enough. I'll always ask for the minimum access needed to diagnose and fix the problem.
What if the issue turns out to be bigger than expected?
I'll let you know immediately with a clear explanation and a revised quote before doing any additional work beyond the original scope.
Do you work with WordPress/Laravel PHP specifically?
Yes, including WordPress plugin/theme conflicts and Laravel application errors, not just raw PHP scripts.
Will you explain what caused the bug?
Yes, every fix includes a short explanation of the root cause, included in all packages, so the issue doesn't come back.
