My senior manager gave me a project migrating a Samsung headquarter in Brazil and he went to Chile for moving a Samsung headquarter.
Brazil project was much more important than Chile regarding cost and size of infrastructure but he believed me and i had to respect it.
the problem was that he had me to go Chile for 3 days to implement CISCO BYOD(Bring Your Own Device) solution while i was doing the Brazil project.
only i had experienced about the solution in our company and there was no time to contract with 3rd company.
I only had 2 days to configure CISCO ISE system with Wireless and it was successful.
While i made a configuration, the local employees was so kind to me. =) they gave me cookies and coffee.
after all, i made a presentation to teach them how to manage the system in English.
I still think it was one of biggest challenge to make a presentation in English because my English skill was not enough.
later, i need to learn how to synchronize ISE with Active Directory.
