Software Developer with Visual Basic and Series/1 experience

United States - Tests: 4

I am a software developer, fluent in Visual Basic 6 and Series/1 assembly language, with a Bachelor of Science degree in Computer Science. I have worked professionally in software development since 2012. My career goal is to maintain a software developer position until I have established enough rapport and reputation in a company to enter management. I would like to eventually pursue a Master's degree in either Business Administration or Computer Science and possibly a Bachelor's degree in some form of Journalism or Psychology. I want to pursue freelance work in journalism and programming outside of my standard 8am to 5pm work hours in order to expand and improve my marketable skills. My writing skills are limited to research assignments that I completed in school and my own weekly blog, but I am willing to pick up small jobs in order to prove my ability.
