Working on a few projects:* Recently published Lockbox (https://github.com/starekrow/lockbox), an easy-to-use cryptographic container library.* Typeractive (no link yet), a mobile-first blogging and full-site CMS platform.* An alternative library/environment for C programming, with extensive thread/process support and optional garbage collection.* A new programming language. The language is currently reminiscent of Javascript and Python, with strong support for embedding other languages as well (e.g. SQL, shell scripts). Initial implementation in C.

General programming work on multiple projects, most related to the company’s primary product line of photo gift design software, with hundreds of thousands of monthly users. Various tasks required extensive use of PHP, Javascript, HTML5, MySQL and/or C++. Some additional work in Python and shell scripting on Windows and Linux.

Lead research and implementation of new technologies to support mobile game development. Development ended up fairly evenly split between Java (on three platforms: ME, SE/browser plug-in, SE/Tomcat), and C++. Some additional work in Ruby.Worked on game servers, build systems and wrote three games: Sonic Jump, Mr. Do's Circus and Pacman Pinball.

Worked on a number of projects:* Technical lead for development of a prototype for a PS2 version of SimCity. Adapted and extended an existing proprietary game engine and toolchain.* Re-implemented Mario Bros., Donkey Kong and Donkey Kong Jr. as a triple-play package on a brand new low-cost coin-op hardware platform. This involved acquiring the original hardware boards, researching chip specs, extracting ROMs and then designing and implementing an emulator capable of operating on comparatively low-end hardware. * Contributed early code, software architecture and technological assistance to a photo booth vending project.* Analyzed, redesigned and rewrote parts of a rendering engine for The Urbz (PS2 game) to meet increased performance requirements.

Us

Lead programmer on two published games: Mace the Dark Age and Gauntlet Legends for N64. Contributed specific expertise to others, including a couple versions of Rush and California Speed.Following those, I conceived, designed and helped to code a cross-platform 3D game authoring environment for PS2, XBox and Gamecube, including the rendering engine, in-game file/resource management, audio support and build system. For this project, my coding focii were on the cross-platform API spec and vector math library, the PS2 rendering engine and the toolchain for importing 3D models, animations and images. I led a six-member team for this effort.

Co-authored NES Toobin'.Coded, and did some graphics and music composition for NES Klax.Designed an interactive graphic and audio editor for the NES, extending the capabilities of the existing development kits.
