אודותינו
I am a 23+ year IT professional, 27 if you include part-time work during the time I was getting my degree. Even so, I have been programming computers for 36 years now because I taught myself how to program in Basic on a Commodore 64 when I was 13. I am looking to build a free lance business by helping businesses in any aspect of their company's IT needs. I can provide turnkey solutions to defined problems or I can gather requirements for mere ideas and run the project through a full SDLC (waterfall or agile). I can learn any programming language quickly (2-3 days usually), if there is a need, because I have learned so many programming languages that they all have a lot of similarities.
