Jack Pettigrew

Independent game development and content creation focused on game development topics and industry coverage. Developed a zero-dependency open-source library (TIL) for C#/WebSockets enabling seamless Twitch integration for games and apps, and demonstrated it by turning chat chatter into in-game actions (e.g., Ducks) on a Twitch live stream using the Godot engine. Created game development content with a dedicated audience (30k+ subscribers) covering games, devlogs, and industry insights. Independently developed multiple games across Unity and Godot, including a Behavior Tree AI study, a Fall Guys multiplayer project, and an ongoing project inspired by Dog’s Life.
