    I'm currently devoting all my energy to Sauce Labs.

    Cofounder, Sauce Labs September 2008 - Present
    Anything and everything: originally coding, then management and product strategy and serving on the board. I've taken out the trash, when necessary.

    Currently my role is Chief Product Officer.



    BitTorrent, Inc. February 2006 - October 2007

    As Client Product Manager (4 months):

    • Moving out of the engineering department for the first time in my career, I guided the releases of BitTorrent 6.0 and BitTorrent's forums.
    • I also helped make the decision to acquire uTorrent.

    As Director, Engineering (14 months):

    • Coordinated the consumer engineering team (about eight engineers) to build BitTorrent's P2P-delivery-based movie store, as well as two major revisions of a self-publishing product.
    • Expanded the consumer engineering team to meet increasing product and maintentance demands.
    • Established a rapid bi-weekly release schedule, and instituted improved revision control and bug tracking processes.

    As Senior Software Engineer (2 months):

    • Co-authored a high-performance BitTorrent tracker in C++ using boost::asio.
    • Helped design and write BitTorrent versions 4.20 through 5.0.9 (in Python, using coroutines for concurrency).


    Senior Software Engineer, Grouper Networks, Inc. September 2004 - January 2006
    At Grouper, I designed and wrote major components of a P2P file sharing application in C#. My most significant contribution was a BitTorrent-like swarming download system to facilitate YouTube-style web-based video sharing.

    Grouper was acquired by Sony Pictures in 2006, and is now known as Crackle.



    Software Engineer, HOTorNOT 2004
    Working closely with the HOTorNOT founders, I built and ran a small quiz-building web app using Apache, PHP, and MySQL. I did all the technical stuff: programming, page layout, system administration, etc.

    After that, I designed and wrote a multi-player online game server in Python, using libevent for scalability.



    Software Engineer, FolderShare 2002 - 2003
    After Audiogalaxy imploded, the founders started another company and hired me to work on their new project. We released FolderShare in May, 2002. I was responsible for a significant portion of all major components of the system through the first several releases, including:

    • A secure, distributed server to broker file transfers and change tracking between clients (in C, using the /dev/epoll interface for fast I/O).
    • The FolderShare client, for which I implemented rsync-protocol peer-to-peer file transfers, as well as basic web server functionality.
    • The FolderShare website, written using Apache, PHP, and MySQL.
    • Encypted client-server and peer-to-peer communications (using OpenSSL), and the associated PKI.

    FolderShare was acquired by Microsoft in 2005.



    Software Engineer, Audiogalaxy 2001 - 2002
    Tom Kleinpeter and I rewrote the Audiogalaxy file sharing system's distributed server in C, using Linux's /dev/epoll. It ran on a couple hundred server machines and ultimately coordinated over a million simultaneous connections.

    After that, I wrote a system to generate artist recommendations ("Other listeners liked..." lists) for the Audiogalaxy web site.

    I also worked with Tom to write a metadata-based content filtering system. It was probably the most accurate content filtering system ever deployed in a peer-to-peer file sharing application, but it still didn't work so well.

    Then I worked on the Unix and MacOS X versions of a new Audiogalaxy client, in C and Objective-C. Shortly before we could release them, though, the RIAA sued Audiogalaxy. They settled out of court, and most of Audiogalaxy was shut down. Years later it resurfaced and was ultimately acquired by Dropbox!



    Contributor, The Freenet Project 1999 - 2002
    Freenet is a censorship-resistant P2P publishing system. I was a regular on the Freenet development mailing list for years, and I wrote a bunch of Freenet-related code, including a Freenet protocol library in C, a once-popular key index, in Perl, and a Freenet web proxy, also in Perl.

    In connection with this work, Brandon Wiley and I wrote a paper, in which we presented some of our early ideas about tailoring Distributed Hash Tables for use in censorship-resistant publishing systems. Brandon presented the paper at IPTPS'02.



    Earlier Work 1995 - 2000
    • At Trilogy, I produced weekly software builds, handled source code escrow, and administrated a bunch of machines running Windows NT and various flavors of Unix.
    • At InCircuit, I wrote networked apps for hand-held barcode scanners like the ones you see at the supermarket.
    • My first hacking job was with a small company that wrote PC software for use with industrial process control systems. I wrote an object oriented database, and a scripting language for stored proceedures. I also got my first exposure to Lisp while playing with a fancy expert system. I was extremely lucky to start out with such a great job!
