Rick Hansen

Software Developer (Senior)

United States

I am a 54 year old software developer working non-stop in the field since 1979. Back then I was converting autocoder to a more high level language called assembler language (BAL) on mainframes Smile | :)

Today I am a lead technical analyst for a large manufacturing company working on the .NET and IBM Java platforms. In the 29 years between then and now I have probably coded in most every language and designed software for a wide variety of applications and platforms.
