Guillermo Aranda

There is no one named Guillermo Fiksman listed as a Business Development Executive at Learnlight on LinkedIn. The only relevant profile found is for Guillermo Aranda, who is listed as working at Learnlight.1

However, the query states that Guillermo Fiksman's LinkedIn username is "guiaranda", which does not match the name on the profile found. It's possible the query contains incorrect information.

Without more details to confirm the identity of Guillermo Fiksman, I cannot provide any additional information about this person or their role at Learnlight. The LinkedIn search results do not contain enough information to answer the query as stated.
