How I work
You know what you get, and what happens if something breaks
Hiring a freelancer is a risk when it isn't clear where the work ends. These are my terms, before you have to ask for them.
Scope is signed before we start
Deliverables, exclusions and acceptance criteria in writing, before the first line of code. Anything added later is quoted separately — it never comes out of what we already agreed.
If the bug is mine, I fix it
At no cost, no matter when it shows up. If it turns out to be a new requirement or an external failure, I tell you and quote it before touching anything.
Support is put in writing
The period is set before we start, based on the size of the project, and it goes in the same document. Nothing is left to anyone's interpretation afterwards.
Frequently asked
Do you work with a contract?
Yes. Before starting we sign a scope document with deliverables, exclusions and acceptance criteria. Neither of us goes in blind.
What if something comes up mid-project that wasn't planned?
It gets quoted as additional work and you decide whether it goes in. What doesn't happen is it quietly slipping in and eating the time we already agreed on.
What if the system fails months after delivery?
If the defect is in my code, I fix it at no cost, however much time has passed. If it's a changed requirement or a third-party service that changed, I explain it and quote it.
How do I know what I get is what we agreed?
Because the acceptance criteria are written in the document we both signed. Nothing counts as delivered until they're met.
