    Writer/ Administrative Support Assistant-Reliable,Accurate

    Philippines - Last active: 28 days ago - Tests: 3

    "Giving up is not an option.Take my hand and I'll raise you up. Let me help you." My four-year career in campus journalism proved my passion in writing.Identifying errors,correcting grammars and even rewriting a whole article is no big deal to me since I worked as an editor-in-chief of a publication for two years. Aside from writing, I offer a strong competency in records management, exceptional interpersonal ability, great proficiency in Microsoft office suite and a keen eye for overall efficiency. I'm one of Jehovah's Witnesses and is actively sharing in the preaching and teaching activity. Excellent communication skills are one of my strengths. As you may notice, most of the projects I worked on are not really related on my course. Thanks to the extensive training I received in various academic contests, and of course to God who benevolently gave His servant an analytic and logical mind, my employers needed only 20 mins or less to lead me on track. With my two brains working harmoniously,I believe, I can be your asset. Lastly, with a General Scholastic Average of 99+ I dig deep, I think well.
