What you getWhat the work actually includes
Reproduction and diagnosis
The bug reproduced reliably before anything is touched, since a fix for a misdiagnosed cause is a coin flip.
Root-cause fix
The actual cause addressed, not a symptom patched over it, so the same bug does not resurface in a different form.
Regression testing
A test added that would have caught it, so it stays fixed through future changes.
Triage for a batch of issues
A backlog of bugs sorted by severity and effort, so the ones actually costing you users or revenue get fixed first.
ToolingWhat we build it with
Chosen because it fits the problem, and because you will be able to hire someone who knows it after we hand over.
- JavaScript
- TypeScript
- React
- Node.js
- Sentry
QuestionsBug Fixing, answered plainly
Do you fix bugs in codebases you did not build?
Yes, after a short paid review to get oriented in the code and confirm we can reproduce the issue — most delay in bug fixing is diagnosis, not the actual fix.
Can you take on an ongoing bug queue, not just a one-off fix?
Yes, either as a fixed batch or under a support arrangement with an agreed response window, so issues do not sit unassigned.
What if the bug turns out to be a deeper architectural problem?
We will tell you before proposing a workaround. Some bugs are a five-line fix; others are a symptom of a design decision that needs revisiting, and you should know which one you are dealing with before we start.
Related workWhat else we build
Most projects need more than one of these, and they are usually cheaper together than sequenced apart.
