    I'm an experienced Python web and desktop application developer, with a few websites under my belt, and 4 years experience. I am working on a cross-platform Python GUI that creates standalone executables from Website projects and Nodejs projects. It's simple and intuitive and has been downloaded thousands of times. The feedback I've received on it is amazing and everyone seems to like it. Work I've done in the past includes Desktop Applications (Java, Python), Web Applications (Python, Django) and game design. In regards to game design, I did game a week challenge not too long ago. The website is at http://simplypixelated.com/. This challenge was designed to get me off my butt and do some video game work! And it worked! I'm friendly and well read, and I love working on interesting things. I learn fast and have experience with lots of programming languages. Programming languages that I know well: C#, Java, Python, Ruby, Javascript, HTML, C, C++ I've worked on a few django websites, one of which is a personal website that is no longer up and the second of which was for a contract job involving Openstack and Horizon. The splash page for that can be viewed here: http://cloudplus.dynastack.com/dyna. Unfortunately, I cannot provide login information. One more that I helped get going was www.readycloud.com, which is a cloud based shipping service that keeps track of orders made for different companies. I've also completed an Android app called Place Locator. It's an app to track places you've been and makes it easy to find them again. It's a free app to download and can be accessed here: https://play.google.com/store/apps/details?id=com.payneattayne.placelocator My personal preference for a language to program in is Python. It's syntax is terse, it's easy to make quick prototypes, and it's very developer friendly for most applications. I love working on new and exciting projects and I love working with new people. I'd love to help you on your mission, whatever it may be.  less

    I would like to offer you my deep knowledge of servers hardware and software, which allows me to fine-tune servers according to their roles, and my ability to anticipate and solve problems in shortest time possible. No Windows please, Unices only, Linux preferrable. Lately my main point of interest has shifted to deploying and maintaining web projects in cloud environments. I am developing monitoring / management tool ( http://m-script.org ) and supporting existing installations, but I am very well familiar with all well known alternatives from both monitoring and cloud management side, so no problem to implement any of them. The point is, I know very well how it works. And how it doesn't, too :) I am interested in any system administration work, especially in cloud environments. The more challenging you setup is going to be, the better. Automated scalability, cross-clouds deployments, combination of traditional and dynamically scalable resources, DNS/Geo balancing - everything is possible, just let me know your needs.  less

    I am a highly-skilled software engineer and computer science graduate with 23 years of professional experience. Software development is my greatest skill and I have an incredible attention to detail and perseverance in getting the job done, and done well. oDesk has recognized me as one of their top Mobile Developers. See the badge on the right of my profile for more information. I've been developing native Objective-C iOS apps for over 3 years. I don't use tools like PhoneGap or Appcelerator. I have direct experience with Apple's policies, device capabilities and account management procedures from publishing my own apps (see my portfolio for screenshots and iTunes links). By hiring me you would benefit from my extensive skills and experience. Technologies change, but first-class analysis, design, development, testing and debugging skills can only be built from many years of hard work and real-life development experience. I work from home in a distraction-free environment using a Mac with dual 23" monitors. For good test coverage I own several iOS devices: iPhone 4S, iPhone 5, iPhone 5s, 1st generation iPad, 3rd generation iPad, retina iPad mini and iPad Air 2. I don't believe you can get the true "feel" of an app by just using the simulator. For client testing, I can use TestFlight to deliver builds throughout the project. Thanks for taking the time to read my profile. I'm looking forward to working with high-quality product designers and creating some great apps together.  less
