    Senior Software Developer & Architect

    Argentina - Last active: 1 day ago - Tests: 8

    Since I begun my career, I've worked for large and small companies with different levels of autonomy and in projects of different sizes. I specially enjoy working on new projects, as I usually got to design most or part of the system, but have worked on improving existing large code bases. I've managed teams successfully it's been a very rewarding experience. The types of systems I have worked on range from command line applications, to desktop, a lot of web apps and backend services (REST & message oriented).

    Ukraine - Last active: 1 day ago - Tests: 2 - Portfolio: 1

    I specialize on Ruby on Rails and front-end development. In spite of the fact I have got a degree in International Journalism and Translation, I worked as QA and IT Sales for total of 3 years (from 2008) and then moved to web development from Jan, 2012. I have performed both back-end tasks (from basic CRUD to making simple APIs or server scripts) and front-end (building static websites from scratch or developing views with twitter-bootstrap). I believe the experience is formed with the quality of the projects, you have delivered, and not with the years of sitting in front of the laptop.

    I turn your ideas into working software.

    United States - Last active: 1 month ago - Tests: 7 - Portfolio: 27

    My dad knew I was a programmer before I did. He bought me that first book when I was about 10. That was 28 years ago. I am a programmer with major project experience in every major language, platform, and operating system. I love working with small companies and startups. Whether you need someone to lead your team, program into the wee hours of the night, or just need someone to talk to, I can help. As your next Virtual CTO or chief architect, I can help translate your ideas into working software. As a full stack programmer, I provide frontend programming, backend programming, mobile programming, and infrastructure buildout. Whether solo or as your team lead, I bring years and depth of experience to your business. I tell people that I am a thinking programmer. Not a "ninja", or a "rock star", or someone who "bangs out code". I am not a "Ruby guy" or a "PHP guy", or an "Agile guy" or a "Waterfall guy". I am just your thinking, capable, competent programmer who sees the world in full color and adapts to the situation. Someone who sits down with you and talks plainly about your goals and what it will take to reach them. If I am the right fit, I say so. If I am not the right person, I tell you that too. Building a technology business requires more than just programming skills. Knowing how to put together servers, infrastructure, networking, security, partner integrations, prototyping, and beta testing are factors which heavily influence your success. So as well as being your programmer, I am also your systems architect and technology advocate. Embedded systems projects are flooding Kickstarter, and I love it. If you need to create and program physical devices using Raspberry Pi, BeagleBone, Arduino, or chipsets from Intel, ARM, and Motorola, I can offer hands-on help and experience. What about video games? Mobile, desktop, or console? I have experience with many of the top game engines including Unity, Unreal, Cry, Game Maker, and many other game development stacks including retro gaming. Or let's create your own game engine and show them all how it's done :) It has been my privilege to work with top brands like Sony, Nestle, NBC, Polaroid, Texas Instruments, Microsoft, and Adobe. As well, I have worked with many promising startups and am honored to be an oDesk Gold Member, an oDesk All-Star, and oDesk Top Rated Freelancer, and an oDesk Verified Web Developer. I have over 2,500 hours clocked on oDesk, a 5-star rating, and am 99% recommended by over 50 clients. Thank you to oDesk and all my clients who helped make this happen for me, it is a HUGE honor. Building hardware and software through oDesk is my full time occupation. I continually learn new ways and approaches to help you avoid costly mistakes and rework in your next project. If you are considering a new venture, a major addition to your existing software, or just need help crossing the finish line, you may be interested in my free ebook titled "Staying Lean". It teaches you how to build your tech startup *without* big budgets and venture capital. The book is free, all I ask in return is the privilege of keeping in touch with you. http://www.benallfree.com/ebook What do I love right now? What should you be looking at to build your next project? Glad you asked! My clients and I love Laravel, Ruby on Rails (RoR), Ionic, Django, AngularJS, Bootstrap, mobile hybrid apps, iOS, Android, PHP, Symfony, jQuery, JavaScript, HTML, mySQL, video, Facebook API, Raspberry Pi, BeagleBone, Andruino, Twitter API, Single Page Applications (SPA), Auth0 (Hosted Identity Management), Composer, Bower, Node and NodeJS, grunt, SASS or SCSS, and much more!

    Experienced Webmaster/Web editor/writer/Copywriter/Proofreader/

    Sweden - Last active: 1 day ago - Tests: 6 - Portfolio: 3

    I am French (bilingual italian) and I have been living in Sweden since 2011. I am currently looking for a position corresponding to my experience either as a Writer/ Webmaster/Copywriter/Proofreader or translator /SEO translator (ideally working from home). After an extensive period of training (in Languages, Literature and Multimedia), I have been working for the last 15 years in the Web sector where I held several different positions (webmaster/web editor/writer/proofreader/copywriter). Over the years, I had to face the permanent challenge of adapting my work to ever changing demands from clients while staying as close as possible to the fast-moving requirements of the media sector. This challenge gave me the opportunity to develop and deepen my skills further allowing me to match as closely as possible the ever demanding needs of the sector. Thus, my skills have become over time more technical and graphic-oriented, although the text itself has remained at the core of my work. A genuine sensitivy for literary work - and more generally literature - meant that my professional work has always been guided by a true concern for rigour and conciseness. Finally, I had throughout my life the opportunity to live in different countries and to evolve in various cultural environments. This gave me an ability to adapt quickly to people as well as circumstances and to develop the open-mindedness required in today’s multicultural world.
