    ★Web | Print Designer | MCSE Certified Computer Tech★

    United States - Tests: 6

    All throughout my college career, I have honed my skills as a Web and Graphic Designer, as well as many others. I'm your stereotypical "get-it-done" computer geek, and my most valuable skill is my ability to diagnose and treat problems through research, either on the web or off of it. I am based in Virginia, but willing to do work anywhere. As I wrap up remaining General Education credits at my university, I hope that ODesk will allow me to market my skills to the people who need them most. My greatest proficiency is in design based applications such as the Adobe Creative Suite, but my knowledge of operating systems, networking, programming, computer troubleshooting and repair, and optimization is more than adequate.

    Hungary - Tests: 1

    Dear Sir or Madame, As you could see in my CV, I have all the skills to fulfill your expectations. In my previous workplaces I mostly worked on administrative field, both in the civil service, and also in the economic sector. As part of the university staff I had to be patient with the students and with the teachers as well, not to mention the developing of my organization skills. During that time I have gained a lot of experiences with people and in being a team player. In one of the biggest bank of Hungary, I have learnt to take responsibility and to be discreet too. On these fields the strictly administration is also a must. My computer abilities I assume are more than satisfying. In my entire life I have worked with computers. My previous workplace was an online marketing agency as a content operator. As philosopher I have a creative and analytical way of thinking, which could be an advantage in any challenge. I am a fast learner too. I have sense of vocation and a strong ability of tolerating stress and keeping deadlines. That is why, I have a firm belief, that I could be a useful part of your team. Yours faithfully, Dániel Józsa
