I have 5 years experience writing Java, during which I've written multiple games, libraries, and more utilitarian programs, along with several Minecraft mods. I have not written plugins for the Bukkit Minecraft Server, but feel it should be relatively easy to learn. If you do not intend to use Bukkit or the other non-vanilla server I'm hearing about, I apologize, as the term 'plugin' more readily applies to them. I have written multiple Minecraft mods, both serverside and clientside. Overall, I am more than capable to create most any custom Minecraft and/or Bukkit plugin. Please feel free to contact me via chat with the details.
