What I Do
This is by no means a comprehensive list of what I know and have done, but it’s a start.
Some projects and code
Cloud Computing & Virtualization
Experience with OpenStack (Nova, Keystone, Glance, Neutron, Cinder) at scale,
AWS, KVM, some VMware
Applications & Technologies
Deep knowledge and understanding of many open source applications and
technologies including: datacenter virtualization, IaaS, SaaS, Big Data,
real-time transaction processing, web systems, RDBMS, NoSQL
I have developed and maintained numerous web facing properties, the specifics cannot be disclosed due to their business nature. I don’t do personal websites, which is why this one looks the way it does.
Technologies and languages I have picked up along the way: Ruby, Python, PHP,
MySQL, PostgreSQL, Perl, HTML, WordPress, Jekyll
Deep understanding of datacenter lifecycle including installation, networking, hardware maintenance, high availability and disaster recovery, advanced configurations, decommissionings and server migrations. I have performed numerous successful server migrations on Linux/Unix systems. Migrations include moving all data, client info, configuration settings, testing and verification with zero downtime.
Operating Systems I’ve worked with: Linux (many flavors, primarily RHEL/CentOS,
Ubuntu, Debian), FreeBSD, Solaris
MySQL/Percona/MariaDB, PostgreSQL, Couchbase: planning and deploying database servers and the databases. Extensive experience creating and maintaining databases, backups, disaster recovery, replication/high-availability (master-slave, master-master, Galera)
Extensive experience scaling and optimizing database servers to handle the
Oprah Effect, as well as Reddit Hugging.
Configuring and installing networks. Troubleshooting networking issues. Planned and installed LAN setups in a datacenter environment.
Technologies: Software-defined networking (SDN) with Open vSwitch (OVS) and OpenContrail, load balancers (F5 BIG-IP, Brocade, LBaaS), firewalls (Cisco, iptables, pf, FWaaS), Switches (Cisco (Nexus, Catalyst), Juniper (SRX, MX), Brocade, Dell PowerConnect), WLAN
