    Javascript | Python | C | Linux

    Australia - Last active: 1 month ago - Tests: 8 - Portfolio: 6

    I am an experienced software developer who has written code in several languages but I presently specialize in Python and Javascript. In the past I have worked in C and C++. The software projects I undertake on oDesk/Upwork are typically of the following nature: - Python and/or Javascript web development with some CSS3/HTML5 layout work - Numeric Python (NumPy) development, code optimisation and performance rewrites in C My primary development platform is Unix (OS X/Linux) and I greatly enjoy working with open source. While first and foremost a programmer, I have broad familiarity with topics such as HTTP/RESTful protocols, TCP/IP, firewalls, web servers such as Apache & nginx. If you are looking for someone to do your homework, I decline all such jobs on principle. If you want to offer me work at rates below my advertised rate, you are probably wasting both your time and mine - unless it is something open-source and really unique. I'm always happy to freely discuss or advise on projects that involve the above technologies.

    Java/C++/Perl professional

    Russia - Last active: 1 day ago - Tests: 11 - Portfolio: 1

    I am Java developer specializing in web projects and I have good experience with different Java frameworks and technologies including (but not limited to) most popular Spring and Hibernate. Also, I created AJAX front-ends based on jQuery, Bootstrap and DoJo on client side and various REST API frameworks on server side. Besides that I like developing and implementing non-trivial tasks that go beyond traditional CRUD action. Due to good knowledge of GNU/Linux OS (and its most popular daemons: Apache, Tomcat, MySQL/PostgresQL, Postfix/Exim, Named/Bind, iptables) I also can offer full support of application life from initial server setup to continued maintenance after main development is complete.

    C++ Designer and Optimizer

    United States - Last active: 1 day ago - Tests: 23

    I'm a self taught programmer with experience largely in C++, but also in Haskell, PHP, Pawn, Lua, and NASM. I have a full decade of work in game modding communities, and have worked on linux patches, game engines, and the intricacies of the C++ compiler and object model for many years now. If you need to squeeze more speed out of your code, or come up with expressive and elegance solutions to unusual or involved problems, that's what I excel at.
