I will debug and fix python javascript c and cpp code
Andy S
About this gig
A script crashes, a request fails, or your code returns the wrong result? I will reproduce the agreed issue, trace its cause and deliver a focused fix you can retest.
I work with Python, JavaScript, C and C++. Send your language, dependencies and a reproducible example first so I can confirm the fit.
Basic: one small reproducible issue in one file.
Standard: one related failure path across up to 3 files, with a regression check.
Premium: one backend failure path across up to 5 files, with focused tests and a clear handoff.
Every package includes the changed source files, a short cause-and-fix explanation, and retest instructions. Scope is based on the failure, not the number of code lines.
My 42 Lausanne training and personal Python/backend projects inform my debugging approach. I do not claim client references or years of professional development experience.
Please message me before ordering with redacted code, the full error and expected behavior. New features, complete rewrites, production deployment, security audits and unrelated bugs are excluded. Revisions apply to the original agreed issue.

I build Python scripts that clean CSV and Excel files, automate repetitive tasks, and connect REST APIs. Trained at 42 Lausanne, I work with Python, C, C++, JavaScript, Docker and Linux. My personal projects include FlowForge for reusable data-cleaning workflows and HookRelay for webhook processing. For small, clearly scoped tasks, I provide source code, verification steps and clear setup instructions. Send me a redacted sample or error message so I can assess the scope before you order.

FAQ
Which languages and frameworks can you review?
Python, JavaScript, C and C++. Python scripts and small FastAPI services are my main focus. Please share the stack first; I only accept work that fits my skills and the package scope.
Should I contact you before ordering?
Yes. Send a redacted sample, your expected result and your environment. I will check the fit, scope and delivery time before you order.
What do revisions cover?
Revisions correct the agreed deliverable against the original requirements. New features, new data structures, unrelated bugs and additional integrations require a separate scope.
Are hosting and third-party fees included?
No. Packages cover development and the stated handoff. Hosting, paid APIs, subscriptions and ongoing maintenance are excluded. Any running costs will be discussed before work starts.
What if the issue is larger than expected?
I review reproduction steps and code before ordering. If a wider dependency or different cause changes the scope, I explain the findings and discuss next steps through Fiverr before additional work.
Do you complete school assignments or assessments?
I do not complete graded assignments, exams or recruitment assessments on your behalf. This service is for legitimate debugging of code you are authorized to change.
