"Daniel is undoubtedly the person I know who knows the most about systems in all their extension. He has deep knowledge of networks, protocols, operating systems, web servers, databases... He is able to diagnose and solve in minutes problems that would take other people hours to identify. He is also patient, kind and knows how to deal with all types of people in complicated situations."
Jose Antonio Tejedor Garcia - CEO at Virtway
"Daniel helped us restructure our systems. We had a very bad experience with our systems provider and had to look for a solution. The option that most attracted us was to migrate our systems to Amazon but we lacked knowledge of both the Amazon environment and system administration concepts. Daniel helped us in the learning and implementation process so that now we are autonomous in administration and we turn to him for everything that escapes our capabilities. It was a great choice."
Enric Serrano Murt - Founder at Optimal Way SLU
"Daniel is a fantastic professional with deep technical knowledge. I would especially emphasize from him his flexibility to always adapt to our requirements, his ability to provide us with different technical solutions to the same problem and, especially, his rigor when performing the work. Without any doubt I would recommend the work of Daniel to all those companies that need solutions with a high degree of customization, as was our case."
Customer (electricity marketer company)
