Master's Thesis: A Python-based Framework for Distributed Programming and Rapid Prototyping of Distributed Programming Models (09/05 - 12/09)
* River is a Python-based framework for rapid prototyping of reliable parallel and distributed run-time systems. The current quest for new parallel programming models is hampered, in part, by the time and complexity required to develop dynamic run-time support and network communication. The simplicity of the River core combined with Python's dynamic typing and concise notation makes it possible to go from a design idea to a working implementation in a matter of days or even hours. With the ability to test and throw away several implementations River allows researchers to explore a large design space. In addition, the River core and new extensions can be used directly to develop parallel and distributed applications in Python.

Faculty Development Fund (9/09 - present)
* Designed and implemented a web app to aid in the Faculty Development Fund application submission process and review using Python and mySQL backend.

MathCandy (6/05 - present)
* Designed and implemented a web app to aid in faculty hiring process and application review using Pythong and mySQL backend. Currently used de facto for all faculty searches in the College of Arts & Sciences.

pyRyll (4/05 - 5/05)
* As part of a two-person team, rewrote the Ryll game (see below) in Python and SDL (with pygame). The network layer was written from scratch and uses peer-to-peer networking, based on multicast, instead of a client-server model.

td2000 (3/05 - 4/05)
* A file sharing program implementation (written in Python and QT) supporting decentralized (no central server) operation using multicast.

AXEmail (10/04 - 12/04)
* As part of a two-person team, implemented a fully-featured web-based e-mail system in Java with a mySQL backend

Book Shopping Agent (03/03 - 05/03)
* Created a book shopping agent in Python with CGI that used Amazon Web Services to perform book searches and make intelligent suggestions based on user's choices.

Node Control System (12/01 - 6/02)
* Designed and implemented a node reservation / check-out system for USF CS computing clusters.

Parallel Compiler (08/01 - 12/01)
* Implemented a parallel compiler for the mySAL programming language that generated Python MPI code

Return to Ryll: A Multi-player game (08/00 - 05/01)
* As team leader on a game project sponsored by Blizzard North, designed and implemented the infrastructure for a cross-platform multi-player persistent-world online action game. Developed a multi-threaded server application to support up to 1024 players. Also developed the graphics and sound libraries using DirectX API under Windows and SDL under Linux

Linux device driver for 3COM 3C905 NIC (08/00 - 12/00)
* Created a device driver for the Linux kernel for the 3COM 3C905B network card based on specifications published by 3COM. (Not to be confused with the real kernel driver; this was merely my own attempt at writing a Linux network driver.)
