A proprietary C#.NET software package developed as the onboard controller for Ground-Penetrating Radar equipment manufactured by US Radar, Inc.

As of January 2010, I've taken over the existing code base to improve and expand upon the software's features and functionality.

A Facebook Connect plugin that lets new and returning users login to your Wordpress site with a single click. Offers pluggable, customizable code that's easy to use as a starting point for more advanced Facebook API functionality.

With over 120,000 downloads and counting, it has given me a place among the top 250 plugin developers worldwide.

A Google Maps interface for Fortress.no's real estate division, developed in collaboration with Bit-Kit.com of Oslo, Norway.

Includes a front-end map for displaying property locations & information to clients as well as a back-end admin panel for repositioning properties & interacting with the underlying database.

A 3D raytracing package for interior design, developed in collaboration with Bit-Kit.com of Oslo, Norway.

This product is still under development; more details will follow as we get closer to launch.

An advanced copy protection library written in native C++ (client side) and PHP/MySQL (server side). Includes:

• Online activation, deactivation, and clock validation
• 128-bit strong encryption and CRC error checking to prevent sniffing or manipulation of activation data
• Digital watermarking to uniquely tag binaries to legal owners
• Hardware-based system validation to prevent license sharing between machines
• Self-modifying binaries to prevent cracks from functioning
• Numerous obfuscation techniques to combat decompilation

Created various tools to assist foreign language study, including:

• Free plugins for the SRS software Anki (written in Python).
• A Windows Mobile app to enable keyboard-driven toggle of the CE-Star language IME
• Japanese glossaries for the Babylon translation dictionary, generated by a custom C++/CLI parser (free downloads):
  • EDICT, the most complete En<->Jp dictionary available.
  • ENAMDICT, an extended glossary of names and places.
  • Heisig Indices for all kanji appearing in RTK vol 1-3.

Developed the name, story, and core marketing concept for a multimillion dollar diamond collection owned and distributed by Rahaminov Diamonds of Los Angeles, CA.

Also created numerous advertising materials in Flash CS4, as well as backend PHP server code for their customer and product database.

A 2D visualizer developed as an add-on module to Dr. Dean Goodman's internationally acclaimed GPR-Slice software (see below). Its highly optimized streaming routines can load and display raw or preprocessed ground-penetrating microwave radar files in excess of two gigabytes - with less than a second of initial load time. It supports hand marker, survey wheel, and GPS navigation data from all of the major radar manufacturers.

Worked as a Nintendo DS gameplay programmer for a small development studio in Kyoto, Japan.

Unfortunately, the publisher has decided to shelve the finished product to make room for the newer Wii console, released within weeks of our "going gold." Unless and until it's officially announced (unlikely), I cannot provide any details.

An MFC Windows application that I developed for geophysicist Dean Goodman at the Geophysical Archaeometry Laboratory in Los Angeles. It's used to manipulate and display 3D volumes of Ground-Penetrating Radar data in real-time. Dr. Goodman's list of over 170 clients from 21 countries includes the US Forest Service, the UK Ministry of Defense, and NASA.

Built this site from the ground up, tying together original code with several well-known scripts under a common look-and-feel.

The original version was built on the b2evolution blog platform, with Gallery2 for photos and ViperGB for the guestbook. This was later migrated to Wordpress, involving a fully custom theme and many handwritten libraries, widgets, and plugins.

The current version is the third major iteration, now based on Suffusion. I've released some of my custom code as free open-source plugins (above).

A 3D online multiplayer video game that I designed and developed at UCSD. As creative and technical project lead, I personally managed our team of four programmers and one artist. I also coded all client-side game logic and the entire graphics engine. The finished product was delivered within ten weeks for a public demonstration before a live audience and television crew.

Software that I developed for Ph.D researcher A. Hoffman to visualize the chemical composition of the human cell with regards to a protein called NFkB. Dr. Hoffman's research uses complex differentials to model how NFkB regulates immune responses in an effort to learn more about various inflammatory diseases. My software helps expedite this by generating human-readable displays from large and complex mathematical data.

A 128-bit Twofish Encryptor/Decryptor chip that I designed in Verilog for one of my Electrical Engineering courses at UCSD.

A 3D interactive application that I developed for the US Department of Defense under a contract through Northrop Grumman/SPAWAR. This software connects to a piece of government hardware and receives positional data on navy battle groups, rendering the data on a relief-map of the earth. The map is generated from satellite images, and can be changed for level-of-detail in real-time.

An application that I developed for the US Department of Defense under a contract through Northrop Grumman/SPAWAR. It is a navy training utility used to simulate the manual controls on a ship-to-aircraft communication system. Inputs are handled via DirectX and client/server connectivity through Windows Sockets.

An 8-bit CPU and corresponding Instruction Set Architecture that I designed and implemented in XILINX. This project was aimed at providing a better understanding of low-level computer architecture and memory management, necessary knowledge for developing efficient real-time software applications.
