    • Created product used in India and Los Angeles throughout the pipeline, from animators to directors.
    • Modified to allow different resolutions and media types for remote sessions.
    • Added annotation features that improved various parts of the pipeline.
    • Added audio/video sync calibration feature that solved longstanding lip sync problems.
    • Created a reusable, cross-platform point placement tool for manually manipulating motion capture data, successfully delivered within four days of request on both Linux and Windows using Python, PIL, and Py2exe. Tool later became part of Locus, a motion capture tracker system used for the face of Dr. Manhattan in the film “Watchmen”.
    • Created a testing framework for cutlist generation to ensure data integrity with regression testing.
    • Maintained various C++ libraries, adding bug fixes for 64bit compilation, media formats, and business logic.
    • Provided substitutes for a legacy libSpBase library to aid future code development.
    Technologies: C++, Python, Boost, PIL, Py2exe
  • Nokia, Senior Software Engineer (2008 - 2009)
    • Created an integration-testing framework for validating separate XMPP servers to determine compatibility problems.
    • Developed Erlang XMPP server code to provide features found in a legacy XMPP server.
    • Ensured that Erlang server modifications made transition transparent to the legacy clients by ensuring protocol compatibility.
    • Created a Messaging Bridge for publishing data updates to internal web services.
    • Created an efficient accounting log system for tracking server utilization.
    • Automated Erlang server initialization code for cluster deployment and data replication.
    • Modified an Erlang Distributed Hash Table (DHT) implementation to provide fault-tolerant key timeouts for both the Java and Erlang API.
    • Certified for Erlang OTP development by Erlang Solutions, Ltd. (http://erlang-solutions.com/) after instruction from Jan Henry Nystrom.
    Technologies: C++, log4cxx, cppunit, boost::asio, iksemel, Erlang
  • PortfolioWatcher, LLC, Co-Founder (2005 - 2009)

  • Perpetual Entertainment, Platform & Server Core Software Engineer (2006 - 2007)
    • Handled critical development tasks to enable sale of Platform/SDK to BioWare; Platform/SDK continues to be sold by PlayGrid.
    • Worked as lead developer for the C++ Platform middleware (PEPSDK), a vital cross-platform API that facilitated the Platform as a N-tier architecture.
    • Coordinated many feature and protocol additions by making the necessary changes within the PEPSDK, game server, and game client.
    • Developed the PepPublisher, a game server process used to report game content and persistence data to the Platform for real-time updates of a player’s progress within the online game.
    • Fixed many elusive multi-threading/distributed race conditions and deadlocks within the game server and PEPSDK to improve game server stability.
    • Created a socket connection thread pool that enforced a real-time Quality of Service with limited memory consumption for efficient XMPP chat communication.
    • Designed protocol agnostic software.
    • Created a distributed integration-testing framework for game server and client functionality.
    • Added localization to PEPSDK API and data structures, including regex functionality.

  • Signature Research Inc., Software Engineer (2002 - 2005)
    • Developed a physics-based global illumination renderer and ray tracer for army test and evaluation programs.
    • Included three distributed systems that were cross-platform and multi-threaded.
    • Used an actor model that conserved memory and avoided global state.
    • Designed and implemented: efficient object communication routines via message passing, distributed memory management with throttling, a spatial partitioning structure, a custom file-based database used to manage intermediate results, etc.
    • Performed all Linux debugging (with GDB, ElectricFence, TotalView, Purify).
    • Worked on the EOView project from conception to ship date.
    • Increased the efficiency of RenderView, a Windows physics-based ray tracer written in Visual C++, by at least ten times after researching, implementing, and testing a spatial partitioning algorithm.
    • Converted a legacy physics-based global illumination renderer that was written for the SGI with IRIS GL and Fortran 77 to Linux with OpenGL and C. Resulting software was stable, cross-platform with dynamic memory allocation, exceeding previous polygon limitations and achieving a speedup of approximately 6x when using hardware acceleration.
    • Maintained and improved PRIMUS, a Visual C++ Windows OpenGL 3D model viewer and conversion tool that aided in-house integration of two physics-based thermal signature prediction programs.
    • Implemented single improvement to achieve 9x speedup when importing MUSES thermal signature files through a more efficient algorithm that used caching and a dynamic lookup.
    • Planned, installed, and configured an eight node supercomputing diskless cluster for distributed development.
    • The High Performance Computer (HPC) was easily expanded to a total of 16 nodes.
