    Perl programmer and systems administrator

    Andorra - Last active: 2 days ago - Tests: 2

    I've been either writing perl or administering systems (or both) for the past 30 years. I've used perl both for administration and large web projects. During that time I've worked for many of London's banks and telecoms companies. I was head of server support for Credit Suisse, undertook desktop refresh project for Merrill Lynch and server architect for Sportal, CTO of FDD, and have held a wide range of senior admin or development roles. I've also been involved with many startups (3 of them my own). I'm creative, understand business imperatives and finances, and have undertaken technical marketing and sales. Recently I've written flooting.com a site devoted to reuse in OO Perl. It's live now, feel free to take a look. I now live in Andorra with my wife and children. I'm quite keen to keep my skills current. If you need someone to quickly grasp what you need and hit the ground running, I may be the right guy for you.
