    Expert complex system architect, C#, C++, DotNet,

    United States - Last active: 1 day ago

    I have over 20 years working on government, military, and civilian systems. I use Microsoft Visual Studio and develop in C++, C#, SQL. I'm a big believer in Microsoft products for large projects that may experience a heavy load or will be used for many years. I work in Java, Javascript, HTML, Brightscript, and can handle virtually any language. I do extensive work with website back-end database and business logic. I believe the key to most business applications is the database schema. I have a lot of experience in video streaming and have developed many Wowza Media applications. I can program Roku channels and integrate them to handle internet streams. I have written several desktop applications used by military and governmental agencies and court systems. My experience goes back to 1975 programming our high school's mainframe which was probably less powerful than an ordinary phone is today. I also have experience converting publications to e-books

    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.

    Javascript | Python | C | Linux

    Australia - Last active: 5 days 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.
