Developed and sold an application for the PokerStars client allowing professional players to play higher volume by decreasing fatigue and increasing the number of games played simultaneously.

• Main features: table management, annoying dialog dismissal, hotkey bindings, and no lag due to extremely minimal CPU usage, unlike competing products.
• The only software on the market to allow the use of a gamepad without causing lag.
• Written in C# with some DLL injection done in C and x86 assembly.
• Made it possible to simultaneously play 40 or more games easily.
• The record (to my knowledge) was 105 simultaneous games using an early prototype of the software. A screencast is available on YouTube.

Profited at online poker, wrote assistive utilities, reverse engineered software clients, and had a lot of fun until PokerStars et al. were forced out of the US market.

• Reverse engineered a smaller site's client, written in Delphi, to extract its unencrypted data stream using DLL injection, C, and x86 assembly.
• Accomplished without any knowledge of Delphi or Pascal.
• Developed significant reverse engineering skills.
• Wrote a bunch of utilities to assist me in Python, C#, and a tiny amount of F#.
• Developed the prototype of the software I would later sell from On The Felt, LLC.
• Continued to grow my reverse engineering skills with the PokerStars client.
• Developed an intimate understanding of Win32 internals.
