Saluton! Mi estas Juan Sebastian. I'm Juan Sebastian from Colombia. I study a degree in Natural Sciences at the Universidad del Valle, in my hometown Cali. Since 2011 I'm an active Esperantist, a Esperanto-speaker. As a registered user I edit es.Wikipedia since 2010, topics related to the music I like, later about biology and culture of my city and province. I love my cats.

Principally I help in the organization of activities and contest related to Free Knowledge and Wikimedia Projects. I'm a founder member of Wikimedistas de Colombia user group, manage the social media pages and represent the group in events or meetings. As member of Esperanto kaj Libera scio I'll attend the Wikimedia Conference this year in Berlin. I was administrator in eo.Wikinews.
