    Good Day and thank you for taking a moment to read my profile! I started working in IT about four years ago as a technical support representative for Simple Helix, a Magento specialist web hosting company.

    Translator & Software developer

    Norway - Last active: 1 day ago - Tests: 11 - Portfolio: 2

    I became fascinated with computers from an early age. Because of this, I also learned a lot of English because all the instruction manuals were in English! At age 13 I started breaking down the software other people had made, and from then and on I experimented a lot and basically taught myself the mind of computers. In regards to languages, I understand quite a few of the European languages pretty well these days and have combined my flair for computers and making software with my interest in languages. I am for the most autodidact and independent. I can, for the most, handle complex projects alone, but I also follow instructions and can work together with other people. I am autodidact in Basic, Turbo Pascal, Delphi. I am familiar with SQL, PHP, HTML, etc.. As for my computer skills, I have myself developed some of the world's fastest routines for managing vast amounts of data... I don't think I should go into the subject of all the software I have used and can use on a professional level (you would be stuck here reading for a very long time). I am in addition basically bilingual. Native in English or Norwegian? I say Yes to both. :) Maybe this can be put to work for you. I really enjoy working with different languages.. Translating and transcribing is not only fun, I still come across a few words that I don't know, and that is the fun part of researching and learning.. I can translate these languages in a professional manner: English, Danish and Swedish ---> Norwegian Norwegian, Danish and Swedish ---> English Norwegian, English and Swedish ---> Danish For short texts, I also offer translation like: Norwegian, Danish and English ---> Swedish. German ---> Norwegian, Danish, English and Swedish. I can offer transcriptions of Norwegian, English and Swedish audio files. Phew. That was a lot about language... Where did it all start you might wonder... Well.. It helps being told that you can not do it. (Don't listen to that you parents out there. Acknowledge the values of your children. Encourage them!) Apart from that, it does help to be stubborn! and travel around a bit is not bad either. Being a software developer is what I really want for my future. Challenges will come my way and I will do whatever I can to meet those challenges in a professional manner. Many old programmers or those taught a language at school see problems and a box they are stuck in. In school, I was the one teaching my teachers. I was the one thinking outside the box to get things done. I can be stubborn sometimes, but in my mind, nothing is impossible. The impossible only takes a little bit longer time. I wish to put my skills into good use and I hope that will be something for you.
