Since 1996, Adrian has been working with Linux – both in his professional capacity as a System Admin in the companies he had worked for as well as his hobby during his spare time. He has built a secure Linux firewall (based on the Slackware distro) on a 486 machine in 1998 which served as his company's main Internet gateway.Since then, he has taught himself PHP programming & developed a fully functional web-based “Staff Leave Application" for his company's internal use, built and sold commercial grade scripts used by online-marketers as well as designed and implemented highly-available MySQL replication across geographical data-centers with automated fail-over monitoring and triggering.In addition to the Linux (RedHat)/System Administration skills, Adrian is also well-versed in the web-application layer, i.e. the LAMP (Linux, Apache, MySQL, PHP) stack. One of his projects which utilizes both skill-sets is the development of the Afterschool.com Education portal which is a custom built Wordpress theme that runs an optimized LAMP stack on secured CentOS server.A strong advocate for the Open Source movement, Adrian's venture into professional training & education is a natural progression in his passion to share his knowledge and experience with others.
