Bio
Wil Loro
Hard to describe the multitude of skills Ivan has. Although working with him on a network job, he had solutions for any IT subjects that might arise, from servers to systems, including networking in general. He's managed to develop several support systems that helped the whole team to run the support business even it not being his direct responsibility. Ivan definitely carries the most diverse toolbox an IT professional can do. Great professional and friend.
