Mael isn't taking new orders for this project right now. Here are some similar projects to explore.
You will get a diagnosed and fixed Node.js or API bug with regression tests
Project details
I will reproduce and repair one bounded defect in an existing Node.js, TypeScript, Python, or API integration, then add focused regression coverage and verify the result.
This project is for a concrete failure with a clear expected outcome: an OAuth callback that stops, an API request that fails, an SDK integration that regressed, or back-end behavior that can be reliably reproduced. You receive a small reviewable change, tests, a root-cause explanation, and exact before-and-after evidence.
I work read-first. Production changes, credentials, live-payment tests, security testing, large feature builds, and open-ended support are not included unless separately scoped and explicitly authorized.

You get:
• Reproduction and root-cause explanation
• A small, reviewable code change
• Tests and before/after verification
• Clear scope, risks, and handoff notes
I work read-first, avoid production changes without approval, and do not claim a fix until it is validated. I am a good fit for a focused integration or software defect with a clear acceptance criterion.
Steps for completing your project
After purchasing the project, send requirements so Mael can start the project.
Delivery time starts when Mael receives requirements from you.
Mael works on your project following the steps below.
Revisions may occur after the delivery date.
Validate scope and reproduce
Review the repository, reproduction steps, environment, and acceptance criterion; confirm the selected tier fits one bounded existing defect.
Isolate the root cause
Reduce the failure to the smallest reliable reproduction and document the affected boundary, assumptions, and constraints.
