I will find and fix bugs in your PHP or nodejs backend

Is your PHP or Node.js backend throwing errors, returning unexpected data, or simply not working as it should?

I'll investigate the issue, identify the root cause, and deliver a clean, tested fix with a clear explanation of what went wrong and why.

What I work with:

• PHP (vanilla, OOP, REST APIs)
• Node.js / Express.js
• MySQL, PostgreSQL
• Docker environments
• Third-party API integrations
• Authentication issues (JWT, sessions, tokens)
• Queue and background job problems (Redis, Bull)

Common issues I fix:

• API endpoints not returning correct responses
• Database query errors or unexpected results
• Async/await and Promise handling bugs
• Authentication and authorization failures
• Integration failures with external APIs

What you get:

• Fixed and tested code
• Clear explanation of the bug and the solution
• Clean delivery via GitHub or direct file
