I have 20+ years of professional IT development work experience. I worked on many different computer systems (Mainframe, MS-dos (since 1.5!), CP/M, Unix, Linux and Windows). I used many different programming languages, the well known, like Cobol, C and Java, and also the less known, like Forth and Focus. I am good in developing databases and create highly optimized SQL queries. Over the years I developed special programs like program generator, compiler and a code analyzer. On the other hand, I developed lot of business applications, since 1999 mostly based on Java and browsers.
