    Industry Experience:
       
      Sonic.net (Santa Rosa, CA)    Software Engineer    June 2013 - Present
         
        Reduced cost of operation via improved automation of telecommunications infrastructure, in a distributed service-oriented LAMP environment.
         
         
      Cyan Inc (Petaluma, CA)    Software Engineer    October 2011 - June 2013
         
        Developed horizontal scalability of concurrent, asynchronous network management system (CyMS).
         
        Collaborated with engineers and architects to identify and eliminate barriers to rapid feature development by transitioning from a Twisted/PB-RPC client interface to a RESTful HTTP/JSON client API.
         
        Solved problems of encapsulation, maintainability, and scalability in formerly unstructured, unmaintainable, monolithic legacy software.
         
        Developed build, unit test, search, centralized logging, and juju charm components for BluePlanet network operating system, with RESTful interfaces.
         
         
      Autonomy / Discovery Mining (San Francisco, CA)    Senior Software Engineer, Technical Lead    May 2008 - October 2011
         
        Heads-down code-writing software engineer and technical lead for four-person engineering team.  Developed software in C, C++, Perl, and PHP for a high-capacity/high-performance LAMP-based distributed data mining system for eLegal Discovery.
         
        Developed intelligent automation of the Extract/Transform/Load (ETL) process, reducing time and cost of operations and enabling advanced setting of client expectations.
         
        Expanded the scalability of ETL, dramatically reducing the overall time to satisfy contracts, and making it possible to accept contracts for processing large data volumes.
         
         
      The Internet Archive (San Francisco, CA)    Software Engineer, System Architect    December 2003 - May 2008
         
        Architect, technical lead, and software developer for the PetaBox Project.  Drove initial development of a very large scale LAMP-based data storage cluster (the PetaBox) underlying all archive.org SaaS.
         
        The PetaBox architecture allowed The Archive to rapidly establish new large (2,000+ servers) data clusters in multiple countries and scale expansion of online, instantly browsable data into the multi-petabyte (millions of gigabytes) range.  The PetaBox architecture is now standard for all Archive datacenters.  As of January 2012, the largest PetaBox instance keeps ten petabytes of data continuously online.
         
        Developed software for detecting, quantifying, and correcting data skew between The Archive's geographically dispersed data clusters, proactively preventing data loss and providing Operations with data consumption forecasts necessary for the intelligent procurement of new data storage capacity.
         
        Configured, deployed, and documented IPVS/Keepalived for load balancing and transparent failover within the archive.org web server farm, enhancing the capacity and reliability of The Archive's web services while reducing demand on IT manpower.
         
         
      Hardpoint Intelligence (Sebastopol, CA)    CTO, Co-Founder    November 2003 - May 2008
