Epic Martial Arts

Owner / Master Instructor

2016 — Current

Starting as a Martial Arts Instructor, I wrote an application to better track student progress. The system included a Touch UI that was intuitive for students as young as 5 to use. Later the application expanded to manage the business side of the studio tracking, historical and projected testing dates, special event sign-ups, camp registration, and finally automated recurring payments.

Created cmdline.org

2009 — Current

Created shortly after the disolution of Dev.5. cmdline.org was a hacking group in the real sense of the word. cmdline.org was created to pool resources and knowledge to help people who wanted to do cool stuff. Community projects included the obvious (searching for exploits), but also included the IPTV Archive, a hosted repo for classic IPTV shows out of production. Geekii, a clone of howtoforge with a wiki format instead of a threaded message board. cmdline.org eventually evolved into it's current small group of security engineers working within Backslash Development.

Heads Up Display, That Doesn't Suck

The new car I bought came with an In-Vehicle infotainment system that could play music from a usb device, but remembering to update the song list on the USB drive seemed like a waste of time. My car includes wifi (disabled by default) that I wanted to use to sync song for me. Once I started looking around the system, I learned the front end was a custom opera browser that interfaces with native code via websockets and json. I'm currently reverse engineering the system so I can implement something that's actually sane.

DevBot

Haskell

circa 2017

Managing the multiple git repositories and projects for the Tox Project as a whole started to become confusing or ambiguous. DevBot was created to help with that, (and because I wanted to learn Haskell.) Features include watching IRC channels for references to issues or pull requests, and providing links to Repos, Reviews, issues, patches, etc. Also included was CI/CD functions support, so developers could run tests/builds without leaving the IRC conversation. And perhaps his most important feature being comedic relief.

Shortly after joining I took over lead development the client, implementing file transfer support with session resuming during crashes network lag. In the core network library; I implemented multi-device support and history syncing, an expanded and improved API, found an existing flaw in friend finding/authentication, and wrote a specification for a more secure, and better optimized procedure.

Pre-Nursing

SAR CMS

Version 2 — PHP5

2014

Just before leaving I created a “Search Notification” system. Often searches in deep backwoods had a severe negative impact on radio communications. Cell phones would occasionally get better connections, but often for only short bursts of time. Text messages became a backup communication channel when radios didn't work. SAR CMS Version 2 started implementing two way SMS so teams in the field could get messages out, as well as stay updated on current search information. This system was intended to function along side the existing callout notification system, which only allowed for messaging at the start of a search.

Student Attendance Tracking Software

PHP4

2006 — 2012

Got tired of signing and dating attendance cards by hand so I developed a tracking system with a touch screen interface to allow students to login. The system saved not just me time, but students as well. It's much easier to find and touch your name on a computer. Especially when your name is printed on your belt color, and you've just turned 3 and are still learning to read!
