Croatian - English Translator, Android application tester, work in Adobe Captivate

I am a native Croatian speaker, and English has been my second language for more than 15 years. My results the Oxford Online Placement Test have shown that I am a proficient English speaker, specifically, that I am a C1 level English speaker.

I have worked for a few months on a major project in which my role was making presentations in Adobe Captivate regarding a real estate related business school. The presentations were esthetically pleasing and consistently made. Examples will be sent if you are interested in giving me an offer in that field.

The most unprofessional of my skills would probably be the "Android application testing" one. I have tested a few simple applications made by close friends, but they weren't really complicated. The reason why I put this as a skill is - I'm an avid Android user, I have two excellent mobile phones (Sony Xperia M4 Aqua, Samsung Galaxy S7) and a tablet (Samsung Galaxy Tab A) which haven't gone into any trouble with demanding apps. But, most importantly, I am a very quick learner, and I'm excellent with technology, given that I'm a third year student majoring in informatics and organization.

Work Terms

I am available to work about 3-4 hours a day, 7 days a week. Concerning payment terms, I'm quite comfortable with PayPal, meaning I would be happy with receiving payments for my work that way. Also my preferred communication style would be either communicating on this site, Google+ or by mail. I am not entirely comfortable with communicating with my contractors over Facebook.
I'd like to add that all of those conditions are not set in stone, and I'm up for a little compromise.
