Unikum Tools

In the past I have been working on, and recently finished a web browser extension. I made the extension as a hobby project and to use for school. The extension adds bookmarks to Unikum.net and is able to show both the schedule and food menu.

The past year I have been working on a marketplace that integrades directly with Minecraft. It has a full web interface build with React (NextJS) and a NodeJS backend. It allows you to sell and buy items from other players and works on 100% vanilla servers!

Hair Salon

When looking for hair salons for myself I stumbled upon a really poorly designed website from like 1999. I decided to make a new response website for them for free using React (Gatsby) and Tailwind. They never replied to my mail tho :(
