Game and Mod Developer

I'm a passionate developer who builds custom features for games and other tools. Developing anything around Minecraft is my main focus, but I also occasionally dabble in roblox dev, but with nothing major to show for that part as I just lost ideas and motivation. I like hard technical problems, especially working on and extending existing open source projects. I'm always looking for projects to contribute to and commissions to work on! Check out my GitHub page aswell! Like what you see? Feel free to reach out to me via the contact methods listed below.
