I will fix bugs in your backend code

I fix backend bugs cleanly, without introducing new ones.

I work as a developer on production financial systems, where a bad fix is worse than no fix. That's the standard I bring to smaller jobs: reproduce the issue first, fix the actual cause rather than the symptom, and leave the rest of your codebase alone.

I can help with:

• Broken or failing API endpoints
• Errors and exceptions you can't trace
• Logic bugs producing wrong output
• Database and query issues (Postgres, MySQL, MongoDB)
• Slow code that needs profiling

Languages: Python, Java, JavaScript/Node, TypeScript

How I work: I reproduce the bug before touching anything. If I can't reproduce it, I'll tell you rather than guess. You get an explanation of what was wrong and exactly what I changed, no silent rewrites, no refactoring files I was only passing through.

Message me before ordering with a description of the issue and I'll tell you honestly whether it's something I can fix.
