Hello, my name is Alex Bisogiannis and a few months ago I joined the CatN team as a Storage Architect. I thought I would introduce myself on the CatN blog and share my experience and the previous projects I have worked on. I recently moved to England from Greece and soon my wife and three children will be joining me in (currently) sunny Farnham, Surrey!

My expertise lie in the following areas, and as my title would suggest I am a specialist storage architect focusing on building scalable, highly available storage clusters to various requirements depending on the project.

  • Extensive experience in the setup, maintenance and ongoing administration of Linux (Ubuntu, RedHat, Debian), Solaris 10, Open Solaris, FreeBSD and Windows Server 2003-2008 operating systems.
  • Setup, maintenance and ongoing administration of Oracle, PostgreSQL and MySQL databases.
  • Administration of Java application servers such as Tomcat and Glassfish to enterprise requirements and standards.
  • Setup, maintenance and ongoing administration of SAN, NAS and other network storage.
  • Design and implement custom ZFS storage solutions on Opensolaris/Illumos and FreeBSD.
  • Web Server clustering, using Apache with pound as the load balancer and caching using Varnish.
  • Extensive experience of creating Private Cloud type architecture based on XEN and KVM.
  • Setup, configuration and ongoing maintenance of high traffic, critical mail servers.

I have been working in the IT industry for over 20 years and of course have worked on various projects. Some of the most notable are as follows.

  • Setting up and maintaining the ClubSeat website, client CRM and ERP systems.
  • Setup and administration of the Greek Ministry of Finance Export Registry Systems.
  • Building and maintaining the server infrastacture for the iPhone application Plaisio, and consulted OTE for it’s webhosting business based on Parallels Zirtuozo containers.
  • A European Union project involving people with dementia, based on the Ecosystem home automation software. Setup and administration of all server infrastructure and remote setup of the Ecosystem on client’s computers.

I’m looking forward to hearing from the CatN testers, and (after we officially launch) our users.
