    I turn your ideas into working software.

    United States - Last active: 1 month ago - Tests: 7 - Portfolio: 28

    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!
