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

    United States - Last active: 4 days 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
