Common questions
Questions buyers actually ask.
Straight answers.
Do you work part-time?
Yes. The work is fixed scope and communication is async, so it fits around your team.
What happens after the sprint?
You own everything. Monthly support is optional if you want me to stay on.
Do you work with existing Terraform and Jenkins?
Yes. I work inside your repositories and review process, not beside them.
Can you start immediately?
Realistically, within one to two weeks of the scoping call.
How do you invoice?
In EUR, from the EU, with intra-community (VAT-compliant) invoicing.
Send me your setup and I'll tell you what I'd check first.
It is technical, and there is no sales script.
