My most famous Plugins are ChatEx, BukkitInventoryTweaks and AdminCMD.
I've also created my own "Systems" over the years for Configuration handling and my own CommandAPI.
Same as my own UpdateChecker API
Since 2016.
I've done a few websites over the years, including this one and the one from my development team Bluemoondev.org
I've started with PHP as backend language, but switched in 2021 to NodeJS.
Since 2014
I'm a little bit experienced with C++ and Rust, also I've done a few Projects with Arduinos and ESP32s using C++.
Currently me and my Team are planning to create a Discord bot written in rust for learning purposes.
