(WIP) Library for generating chains of reports with AI.

AI Reporting Library

Web application that helps cancer patients determine their best treatment options. It's fully customizable via a CMS and uses a logic tree like system to show determine the best options for the user.

OncoLife Survivorship Care Plan

Application for provisioning apps with Docker based on Platform.sh’s spec. Meant as a tool to be used for local development. The original version was created with Python and was later rebuilt with Golang.

Platform.CC

Web application for viewing real-time game play statistics for the popular online video game, Final Fantasy XIV. At its peak usage the application had 10-20 concurrent users, and processed about 200,000 log lines per hour.

FFLiveParse

HTTP/FastCGI proxy with a cache extension. The cache is meant as a very simple and lightweight substitute to Varnish and supports edge side includes (ESI).

CProxy & CProxy-Cache

A simple 2D game library utilizing SDL2. Created as a learning exercise to better familarize myself with C++, game development, and library creation. It is worth noting that a game built with this library was ported to Android.
