SalesJobs.com – CTO / DevOps System Administrator – Manhattan Beach, CA (2006 – Aug 2017)
As the CTO and System Administrator, returned a crippled niche market job board site to a fully functioning and successful business. The architecture was comprised of over 2 dozen Unix servers, dozens of applications and protocols, as well as self managing standalone and cron scripts. All aspects of the system architecture and functionality were redesigned and streamlined to produce a more flexible and manageable product, resulting in a job board that is currently the largest and most successful niche employment site on the web.
All servers are connected in a private LAN network as well as available to the public on the appropriate NIC and ports (80, 443, 22, etc). The service included Apache2 web servers (V2.4), Apache::ASP and Apache2/mod_perl2 front end API utilizing modern OO methods, MySQL/MariaDB databases in a master/slave configuration as well as backups, DNS servers configured as primary and secondary (DJBDNS), access servers providing customers with customized XML and Restful API feeds, multiple email servers (MTA) using DJB Qmail in a multi-node, multi-domain, channelized configuration. All servers are protected with firewalls both at the server level with restrictive iptables rules as well as the colo routers firewall (port specific access).
Over the years I’ve managed to consolidate all hardware to just a few larger more robust Sun Microsystems M4 servers, all running Fedora 24 OS. Most recently I’ve pushed the service into the AWS cloud infrastructure using EC2 and RDS instances, developing and implementing strategies for CD/CI using AWS CodeDeploy, CodePipeline and S3. I manage and maintain all aspects of this service, managing AWS frontend technologies, hardware purchasing and upgrades, initializing OS instances, loading all supporting Linux core applications, installing custom application programs and services, testing, sending to the colo facility where it is plugged in and readied for cutover. I write all the code, performing all the updates, troubleshoot all the problems, as well as implementing new concepts, code and techniques along the way.
