I needed an urgent website backup and he delivered fast and professionally. Communication was clear, everything was done exactly as promised, and he even double-checked that the backup was working properly. Reliable, efficient, and stress-free service.

David did an excellent job helping me ensure Proxmox and pfSense were working properly with the vLAN and VPN configuration I needed. He's very well versed in these technologies, how they work together and the best practices needed to avoid issues in the future.

David is very knowledgeable and was able to immediately address the issues I was facing in pfSense. He not only resolved everything, but explained it along the way so I could better understand what's needed in the future. I will definitely hire him again.
Hilfreich?
