I will fix bugs in your python, javascript or automation script


About this gig
Your script throws an error, hangs or returns the wrong result, and you have already spent hours on it. Send it over and I will find the cause.
WHAT I FIX
Python, JavaScript, Node, Bash and automation scripts. Runtime errors, crashes, wrong output, infinite loops, encoding and import problems. Broken API calls, database queries, scraping scripts and cron jobs. Also scripts that take minutes when they should take seconds.
HOW IT WORKS
- Send me your code and tell me what it should do.
- 2. I reproduce the bug on my machine.
- 3. You get the fixed code, tested, plus a short plain language explanation of what was wrong.
WHY ME
I am a developer working daily with Python automation, data processing and MQL5 trading bots. I do not patch symptoms. I tell you the root cause so the same bug does not come back next week.
SCOPE
Basic covers one bug in up to 100 lines. Standard up to 3 bugs in 400 lines. Premium up to 1000 lines including refactoring and tests. Larger codebase? Message me first and you get a custom offer with a realistic deadline.
Basic is delivered within 24 hours. I work in English and German.

FAQ
What if you cannot fix the bug?
Then you do not pay. I look at the code first and only accept the order once I am confident I can solve it. If I get it wrong anyway, I cancel and you get your money back, plus whatever I found out along the way.
Do I have to share my whole codebase?
No. The failing file plus the error message is usually enough. Send only what you are comfortable sharing, strip out keys and passwords first, and I will ask if I need more context.
My script is bigger than 100 lines. What now?
Message me before ordering. I look at the size and the error, then send a custom offer with a realistic price and deadline. Better that than you buying Basic for a job that does not fit in it.
Do you speak German?
Yes, I am a developer based in Germany and a native speaker. Write me in German or English. Everything runs through Fiverr chat, so the full scope stays in writing and nothing gets lost in a call.
