What information do you need to get started?
Please send the error message, steps to reproduce the bug, what you expected to happen, and access to the relevant code. A screenshot or short video can also help. Please contact me before ordering so I can confirm the scope.
Can you fix any Node.js or NestJS bug?
I work on Node.js, NestJS, and TypeScript backend issues, including API errors, database logic, and application crashes. I’ll review your issue first to confirm that I can reproduce it and that it fits the selected package.
Which package should I choose?
Choose Basic for one small, reproducible bug; Standard for one bug with additional tests; or Premium for up to two related bugs with tests. If you’re unsure, send me the details before ordering and I’ll recommend the right option.
Will you explain what caused the bug?
Yes. I’ll explain the cause I found, what I changed, and how I checked the fix. Detailed comments throughout the code are available as a Gig Extra.
What does a revision cover?
A revision covers adjustments to the fix for the issue we agreed on, if it doesn’t work as specified. A new or unrelated bug is a separate task, and I can quote it after reviewing the details.
