I'm a hobbyist mod developer, I do Minecraft modding in my free time.
I sometimes do modding commissions (this is highly dependent on the case) contact me if you're interested. I have a small portfolio of public comissions on the mod page.
I have a few long-term projects and mods I maintain, you can find these in the mods tab. Generally my source is on GitHub, there is not much I do that is not open source.
