How a project runs
Day one
You own everything from day one
Code, accounts, servers and keys are in your name.
First 5 days
Five-day refund
If in the first five days you feel this is not working, tell me and I refund what you paid.
Weeks 1–2
A small first milestone
We start with one or two weeks of work. If either of us wants to stop at the end of it, we stop — you keep everything built so far.
Every week

You see working software every week, with a short written update. Calls when they help, not on a schedule for its own sake.

Free bug fixes for 30 days
Bugs in what I delivered are fixed free for 30 days.
