I first started using computers in 1980 in Kevin Street College, Dublin, getting my first job in 1984 as a systems programmer (C on Motorola 68010) of a proprietary operating system. I stayed in programming until 1992 when I switched to system administration of a mixture of Unix and Unix-like systems. Since then at home and at work I have continued my administration of Unix and Unix-like operating systems: SunOS/Solaris, Linux, HP/UX, MacOS. However I have continued to use and enhance my programming skills and regularly use several computer languages (C, PHP, JavaScript, SQL, awk, sed, Bourne shell, Python) at home and at work.
