Packet Clearing House, San Francisco, CA - Software Engineer

August 2004 - November 2005

Architected and implemented software to remotely install, update, and synchronize systems and applications running on globally distributed hosts, facilitating the development and growth of PCH anycast cluster from experimental phase to production platform with over 80 hosts at 25 sites worldwide. This platform is the basis of critical DNS infrastructure including the I root, the .biz TLD, and numerous ccTLDs.
Helped maintain and debug Inter-NOC Dial-By-ASN VoIP phone hotline system. This included using tcpdump and Ethereal to diagnose subtle bugs in early firmware revisions of the Cisco 7960 IP Phone network stack, and working remotely with Cisco engineers to design and implement workarounds.
Set up wiki and contributed to effort to document organizational practices, hardware configuration, and software internals.
Collaborated extensively online with coworkers, contractors, and network operators scattered around the world.

Skotos Tech, Inc., Berkeley, CA - Systems and Security Engineer

May 2001 - December 2003

Wrote code in a variety of languages to integrate open source software with existing Skotos systems. Examples include modifying PHP source of vBulletin to use the same authentication credentials as the core Skotos web site, and adapting MUDzilla, a telnet client written in XUL and Javascript, to seamlessly connect to Skotos games.
Handled aspects of security including risk assessment, policy definition, firewalling, system patching and hardening, intrusion detection, and incident response.
Maintained numerous services including DNS, mail, web, databases, NFS, SSH, and DGD mud/chat.
