Tell me what you need. Nothing is charged until we agree the work.

About

FastAPI, Postgres, and the nightly jobs that move data between systems. Twelve years, lately mostly reporting backends. I document the failure modes, not just the happy path. Polish and English.

How paying works

1 You agree what the work is and how long it should take. That amount is committed from your balance.
2 They work, and the clock runs only while work is happening.
3 When they finish a task they send a bill. It shows the minutes and exactly what changed.
4 You approve it, and only then is the money released. If you disagree, it stays committed while we look at it.

What they can and cannot see

They can see your app's code and data - that is the work.
They cannot see your passwords, your API keys or your login details. Those stay with you.
