EnderIO is a massive tech mod, with a magical theme focused on souls and industry. The most distinctive feature is its conduits, which allow transporting items, fluid, power, redstone, and more within a single block. Since 2013 when CrazyPants started the mod, it has grown into one of the largest tech mods, with content for almost every aspect of the game.
I joined the mod in 2014, mostly as a wiki editor, and doing small pull requests. Soon I was brought on as an official developer, and later when CrazyPants had less time to devote to the mod, the main developer. Eventually, I also had less time to devote to EnderIO, so the torch was passed on. But I remain an active part of the team, mainly running the discord server, website, and continuous integration services.
Since August 2013, EnderIO has been downloaded over 30 million times from CurseForge.
