Mutual NDAs executed before accessing repositories or infrastructure. We never share proprietary architecture details, server IPs, or client configurations. All work includes reproducible shell commands and handover runbooks.
Frequently Asked Questions
How soon can we start working together?
Depending on ongoing client commitments, new projects typically kick off within 3 to 7 business days following scope approval. Emergency production outages are addressed with priority.
Do you sign Non-Disclosure Agreements (NDAs)?
Yes, absolutely. Mutual NDAs are executed prior to reviewing proprietary source code, credentials, or private cloud environments.
What cloud providers and operating systems do you support?
We specialize in modern Ubuntu Server (24.04 and 22.04 LTS), Debian, and CentOS/AlmaLinux hosted across DigitalOcean, AWS (EC2/RDS), Hetzner, Linode/Akamai, and Google Cloud.
Can you help with emergency server down / 502 Bad Gateway issues?
Yes. Emergency incident diagnostics are prioritized. Submit the inquiry form with 'Emergency Incident / Bug Fix' selected for expedited review.
