Looking for Systems Admin for Ubuntu Dedicated Server
No tasks, communication, or deliverables for multiple years. The contract had been initiated by a developer who left our team years ago. The freelancer kept logging 1 hour per week without any actual work, which remained unnoticed until a recent audit. This is unauthorized billing and caused long-term financial damage.

Klevin helped us provision and manage our Unix servers, and built a Let’s Encrypt SSL script to handle certificates across hundreds of domains. He was efficient, reliable, and made the whole process seamless. Highly recommended.
