Major Hayden - a social nerd

SYNOPSIS

major [--admin systems|database] [--contributor] [--developer] [--educator]
[--leader] [--other]

SUMMARY

I’m a Linux Engineer with skills in database administration, system administration, application development and leadership. I enjoy connecting people with technology solutions that are easy to use, affordable, and sustainable over time. I'm familiar with, and a huge supporter of, the DevOps culture and how to make it work with a large team in a fast paced environment.

My current focus at Rackspace is information security. As the Chief Security Architect, I lead a team of senior Windows, Linux and networking engineers who are dedicated to increasing security within Rackspace and for our customers. We provide critical security advisement to the business as a whole and we fuel technical security projects that allow the company to reduce risk, reduce product development cycle time, and increase customer confidence.

I was previously working on the OpenStack project and its integration with Citrix Xenserver and Nicira's networking stack. I also maintained our high-availability clusters, Debian packaging and various system tools and scripts. Our team created a highly automated continuous integration system with Jenkins that allowed us to test and deploy new code much more rapidly than before.

Although some are Rackspace-specific and proprietary, I release a large amount of code on GitHub as open source.

--developer

supernova
The supernova wrapper for novaclient allows a user to store credentials for multiple OpenStack environments and use them with simple command line arguments. Credentials can be stored in system keychains for increased security.

mysql-json-bridge
Allows for MySQL results to be delivered via JSON. Consumers need no access to the databases being queried.

mysqltuner
MySQLTuner is a script written in Perl that will assist you with your MySQL configuration and make recommendations for increased performance and stability. Development has gone a bit dormant but I do what I can to keep it updated.

Currently focused on Python for work with OpenStack components but able to work with Ruby, PHP, Perl, and shell scripting if needed.
