I’m always open to listen to new ideas and views and try to understand them and learn of others points of view. I’m a very good friend. I’m always there for my friends, ready to listen, give advice and help with their problems. Some people think I’m feeling less, some others think I’m cold in my reactions; some think I’m simply coldblooded. In reality, I’m not, I’m just someone who is good at hiding his feelings and who knows how to control his temper. I love watching movies, listening to music and hanging out with friends on weekends.

I've been designing websites, graphics, spreadsheets and software for over 17 years, over 95% from scratch. My specialty is the area having to do with "Direct Response" methods of lead generation, having studied almost every Dan Kennedy book and dozens of self-study courses over the years. I eat, breathe, sleep and dream sales and marketing. You think like an entrepreneur, and so do I...because that's almost all I've known for over a decade. I've been self-employed in some form my entire adult life. Borderline-obsessive work ethic is just another day at the office. I've gone through Tim Ferriss' "4-Hour Work Week" almost a dozen times.

It was on this day that my disdain for authority was born...) - I own (and actually completed) more sales, marketing, real estate investing, and real estate agent training courses than I can count (over 100 at least) - I hired a professional sales and marketing coach for approximately two years while practicing real estate, and amassed a well-rounded business education along the way - Barely old enough to vote, I spent 3 years selling telecommunications service and building sales teams I've also spent more time than I can count on: - Writing custom email campaigns - Writing eBooks and Free Reports for website give-aways - Designing custom graphics, flyers, and advertisements - Designing website elements (logos, buttons, banner graphics, backgrounds, etc) - Copy writing / sales letters (long- and short-form) Long story short: I have a strong background in the many aspects of internet-based sales and marketing, I love sales and marketing, and I'm a stickler for details. Send me an interview request today and let's see how I can be an asset to your project! I'm very familiar with the following languages and tools (if your project requires them): - HTML / PHP / CSS - Javascript / jQuery / jQuery Mobile / AJAX - Adobe Photoshop / PSD-to-HTML - MySQL databases (and website integration) - Microsoft Excel (I've designed hundreds of custom spreadsheets and 3 complete software solutions for myself and clients) If you're looking for a developer or content writer with a strong background in the finer points of sales and marketing, one with an obsession over the details, one with a thorough understanding of what it takes to generate you more business and get you more email subscribers, send me an interview request today and let's see if we're a match.

    English/Japanese and Japanese/English Translator

    United States - Last active: 1 day ago - Tests: 4

    (能力レベルを見せるように、日本語話者のために「Overview」は日本語に翻訳されました。日本語訳は原文の下にあります。) Writing & Translation: I can translate things such as websites, computer programs, games, applications, and so on. I can also proofread in English. I type 72 words per minute. Web Development: I know a good amount of HTML, JavaScript, and CSS to produce and design websites. I haven't had the opportunity to use PHP very often yet so I am very amateur at making login systems and profiles at the time. Game programming: I am a nonprofessional game programmer. I have created PC games before(Mann is one of the first ones), and am in the process of creating another bigger game(all in GameMaker Language, however I have translated for people using C++). Graphic art: I know how to use graphic programs like Paint and Photoshop, presentation programs like PowerPoint, and 3D programs like Daz3D. A lot of the graphics on my websites, games, and programs were made with these programs. Voice talent: I am a singer. Also, I sing to my own lyrics and music(either custom made or made from sound-loops). I can change my voice and sound like a cartoon character or an anime character. --------------------- 書き込みと翻訳:ウエブサイトとかコンピュータープログラムとかゲームとかアプリを作ることが出来ます。それも、英語で文法チェック出来ます。 ウエブ開発:HTMLとJavaScriptとCSSは十分知っていますので、サイトを作ることが出来ます。PHPと多くの経験がありませんので、セキュアログインシステムなどは作ることが出来ません。申し訳ありません。 ゲームプログラミング:非専門家ゲームプログラマです。パソコンゲームを作ったごとがあります(マンは最初の一つでした。)そして、新しいゲームを作っています。(すべてのゲームはGameMaker Languageで作られましたが、他人のC++で作られたソフトを翻訳しました。) グラフィックアート:ペイントとかPowerPointとかDaz3Dのように3Dソフトを使う方法が知っています。私で作ったサイトとかゲームの多くのグラフィクスはこのプログラムで作られました。 ボイスタレント:私は歌手です。そして、自分の歌詞と音楽(カスタムメイドなりサウンドループなり)で歌います。声を変えて、カートゥーンキャラクターたーとアニメキャラクターのように聞こえます。
